Load analysis and structural considerationBee Key Verma
The document discusses various types of loads that act on buildings including dead loads, live loads, wind loads, seismic loads, and temperature loads. It also describes different structural systems for high-rise buildings that efficiently transfer loads, such as braced frames, shear walls, core and outrigger systems, bundled tubes, and diagrid systems. Basements are discussed as providing additional space in buildings for parking or other functions.
The document outlines key design criteria for high-rise buildings, including:
1. Limit states design philosophy to ensure structures can withstand worst case loads during construction and usage with an acceptable probability of failure.
2. Consideration of construction sequencing and methods to allow for rapid erection given the large capital costs of high-rise projects.
3. Accounting for all expected gravitational and lateral loads over the building's lifetime, including combinations of dead, live, wind and earthquake loads.
IRJET-Lateral Stability of High Rise Steel Buildings using E TABSIRJET Journal
This document summarizes a study on improving the lateral stability of high-rise steel buildings using different bracing systems. A 15-story steel building model was created and analyzed using ETABS software under wind and earthquake loads, with no bracing, X-bracing, and V-bracing. Results found that displacement was higher without bracing compared to braced models. X-bracing experienced higher lateral loads under wind, while V-bracing performed better under earthquake loads. More research is needed to further evaluate bracing systems for improving lateral stability of high-rise steel structures.

Study of Eccentrically Braced Outrigger Frame under Seismic ExitationIJTET Journal
Outrigger braced structures has efficient structural form consist of a central core, comprising braced frames with
horizontal cantilever ”outrigger” trusses or girders connecting the core to the outer column. When the structure is loaded
horizontally, vertical plane rotation of the core is restrained by the outriggers through tension in windward column and
compression in leeward column. The effective structural depth of the building is greatly increased, thus augmenting the lateral
stiffness of the building and reducing the lateral deflections and moments in core. In effect, the outriggers join the columns to the
core to make the structure behave as a partly composite cantilever. By providing eccentrically braced system in outrigger frame by
varying the size of links and analyzing it. Push over analysis is carried out by varying the link size using computer programs, Sap

subjected to strong ground motion. Maximum stiffness, strength, ductility and energy dissipation capacity are provided by
eccentrically braced frame. Studies were conducted on the use of outrigger frame for the high steel building subjected to
earthquake load. Braces are designed not to buckle, regardless of the severity of lateral loading on the frame. Thus eccentrically
braced frame ensures safety against collapse.

This document provides an overview of the process for casting a flyover pile in situ. It begins with surveying the location and excavating the soil until bedrock is reached. A temporary steel case is placed and bentonite is used to prevent soil collapse. Reinforcing steel is assembled into a circular cage that is lowered into the excavation. The steel case is filled with concrete in stages. A load test is performed to ensure the pile can support the intended loads. Finally, a pile cap is constructed by placing concrete over gravel fill to connect multiple piles.
The document discusses various types of loads that act on buildings including dead loads, live loads, wind loads, seismic loads, and temperature loads. It also describes different structural systems for high-rise buildings that efficiently transfer loads, such as braced frames, shear walls, core and outrigger systems, bundled tubes, and diagrid systems. Basements are discussed as providing additional space in buildings for parking or other functions. Cores integrate essential services like elevators, stairs, and utilities.
This document discusses the demand for and development of high-rise buildings. It defines high-rises as buildings between 35-100 meters tall or having 12-39 floors. Over time, demand has increased due to factors like scarcity of land and technological advances enabling taller structures. Structural systems have also evolved from bearing walls to more sophisticated exterior tube and outrigger designs that allow for greater heights. The core, composed of elevators and other services, plays an important role in resisting lateral wind loads. Modern skyscrapers often use tube systems that move columns to the perimeter, creating a hollow rigid structure.
The document provides information on the construction and erection of bridge elements such as prestressed concrete girders and deck slabs. It discusses casting of bridge girders using steel molds, various launching methods for erecting girders including using launching girders, and the balanced cantilever method of construction where bridge segments are constructed in a balanced manner from each pier until the two halves are joined. It also covers different types of bridge decks and systems used for structural steel girder bridges.
The basic components and parts of a bridge include the superstructure, bearings, and substructure. The superstructure includes the deck and girders that support the roadway. Bearings allow movement between the superstructure and substructure and transmit loads. The substructure includes piers, abutments, and foundations that support the superstructure and transfer loads to the ground. Piers are vertical structures that support spans while abutments retain earth at the ends of the bridge and transfer loads into the ground. Foundations distribute bridge loads evenly into the soil or rock.
The document describes the construction process for columns, slabs, and beams in reinforced concrete structures. It discusses the materials used and the typical steps involved, which include:
1) Layout and formwork installation
2) Placement of reinforcing steel based on structural designs
3) Pouring and finishing of concrete
4) Curing of concrete to gain full strength over 28 days
The columns transfer loads vertically through reinforced concrete that is mixed on site or delivered by ready-mix trucks. Slabs and beams are constructed through similar processes of steel reinforcement, formwork, concrete placement and curing.
The document discusses earthquake resistant structures and techniques. It provides an introduction and table of contents on the topic. Key points include how seismic effects like inertia forces impact structures, how architectural features affect buildings during earthquakes, and seismic design philosophies like allowing minor damage in minor quakes but preventing collapse in major quakes. Techniques discussed are use of shear walls, vertical reinforcement, base isolation, energy dissipation devices, and designs to keep buildings upright during shaking.
The superstructure of a building consists of elements above the foundation like beams, columns, lintels, roofing and flooring. Beams are horizontal members that carry loads and transfer them to columns or walls. Reinforced concrete beams are designed to resist both bending moments and shear forces from loads. There are different types of beams like simply supported, fixed, cantilever, continuous and overhanging beams which are designed based on how they are supported. Columns are vertical load bearing members that transfer loads from beams and slabs to the foundation. Common column types include long, short and intermediate columns. Lintels are short horizontal members that span small openings like doors and windows and transfer loads to masonry, steel or reinforced concrete

Prefabrication involves assembling components of a structure in a factory and transporting them to the construction site. It has advantages like reduced cost, material, and time compared to traditional construction. Precast concrete components like walls, beams, slabs are produced in a controlled factory environment and assembled on-site. Prefabrication requires planning for transportation, lifting equipment, installation, and connections between components. While it offers benefits, it also has challenges like handling of large precast units and achieving monolithic joint connections.
This document discusses various structural members and concepts in building structures. It describes columns, beams, trusses, slabs, lintels, headers, arches, vaults, and structural connections/joints. Columns support axial loads and distribute load to foundations. Beams span horizontally and transfer loads to columns. Trusses use triangular frames to handle both tension and compression forces. Slabs distribute loads across multiple directions through shortest and stiffest routes. Arches transfer axial loads through curved elements to arch abutments. Vaults form arched coverings with barrel or groin configurations.
The Turning Torso in Malmo, Sweden is a residential tower that twists 90 degrees from bottom to top. It has a central concrete core and cantilevered floor slabs that are supported by an exterior steel spine. The steel spine transfers wind and seismic loads to the core. The tower was constructed using an automatic climbing formwork that moved up with each completed floor. The complex twisting geometry required a double curved glass and aluminum facade with windows that lean up to 7 degrees to accommodate the building's twist.
Precast concrete is produced by casting concrete in reusable molds away from the construction site. This allows for mass production of identical components like beams, floors, and walls in a controlled environment. When complete, the precast components are transported and lifted into place at the construction site. Using precast concrete can speed up construction time and reduce costs compared to traditional cast-in-place concrete through economies of scale in production.
This document provides specifications and information about beams and columns used in construction. It discusses reinforced concrete columns and different types of columns based on height-width ratios and shapes. It also describes the construction process for RCC columns. For beams, it defines reinforced concrete beams and classifies beams based on their supports. It discusses different types of beams and the construction process for beams.
The document discusses various methods for constructing and erecting bridge elements. It describes the construction of prestressed concrete girders including casting them on site and using precast panels. Common bridge girder erection methods are also summarized, such as using launching girders to shift girders into place span by span. Balanced cantilever construction is explained as building out cantilever segments from each pier until the two halves meet in the middle.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
