1. The document discusses the building system for a plane frame structure. It uses steel H-shapes for columns, beams, bracing, and tie beams arranged in a rigid frame to transfer loads from the roof and floors to the foundation.
2. For multi-floor structures, the frames can be pure rigid, use rigid horizontal connections with hinged verticals plus bracing, or use hinged joints for both with bracing in both directions. Column and beam shapes include H-shapes, boxes, crosses, and pipes.
3. Bracing includes both flexible rod steel and stiffer section steel. It is used to provide rigidity and transfer horizontal forces. Details are provided for nodes, bracing,
3. 1.1.2. Mechanics Principle
Plane Frame Structure is the Transverse frame which formed by Column and Beam , to ensure the longitudinal stability arrange the
Column bracing and Roof bracing.
Steel Frame
Frame Column and Beam used H-shape steel ,the loading pass to foundation through column and beam.
Bracing ,Tie Beam
Rigid bracing used the hot roller section steel ,general used angle steel , flexible bracing used rod steel .Tie Beam used circular
pipe which formed closed system together with bracing.
Roof Purlin , Wall Girt
General used C section steel or Z section steel , bearing the loading passed from wall and roof panel and pass the load to column
and beam.
1-1-3. Plane Frame Basic Form
17. 1-2-2 Mechanical Model
A. Pure Rigid Frame: Both Vertical and Horizontal are used rigid frame.
B. Rigid Connection-Bracing Frame : Horizontal used rigid connection , Vertical used hinge joint and arrange bracing on vertical
used for pass the horizontal force
C. Frame of Bracing Type :Both Vertical and Horizontal are used hinge joint ,both direction arrange bracing to pass the horizontal
force .
D. Sometimes to ensure sufficient rigidity, in the rigid frame also set bracing .
Frame Column
Frame Column can used H shape ,Box Shape , Cross-shape ,Pipe ects ,all the force from above pass to ground by frame column.
Frame Beam
Frame Beam used H shape ,the force from roof and floor pass to column through Frame beam.
Bracing
18. Bracing used hot roller steel ,the function is pass the horizontal force to ensure the rigid of frame.

2-2 说明
Bracing divided in flexible bracing and rigid bracing , flexible bracing fabricated by rod steel which must tighten during installation,
mainly used for Plane Frame , rigid bracing fabricated by Section steel which used for high rise building, strength bracing below
crane beam .
