合兴安徽钢结构浅谈钢结构中对框架结构的一般说明

发布时间:2015-11-2 10:03:47 浏览次数:479

1.框架-支撑和框架-剪力墙是最常用的。它们都是双重抗侧力体系。


在地震区,要求用双重抗侧力体系。不宜采用铰接框架加支撑(或剪力墙)。在非抗震区,可以用铰接框架加支撑或剪力墙。在强震区结延性很重要。混凝土剪力墙的性能不如支撑框架。


2.房屋既要承受竖向荷载,又要承受水平力。承受竖向荷载靠梁、柱,承受水平靠抗侧力构件。


3.纯框架体系最简单,它的延性好,抗震性能也是最好的(26层的北京长富宫饭店就采用纯框架)。它的缺点是用钢较多。但对多层建筑特别是两个方向开间较多的,纯框架用钢并不多。在日本60米以下的钢结构大部分采用这种体系。


4.高层建筑结构的特点是,结构受水平位移控制,结构设计主要使水平位移不超过控制值。


5.在住宅钢结构中,抗侧力结构主要有三种:钢架、支撑框架、剪力墙。


6.这里的“框架”都是指节点钢接的框架。严格说来,框架包含钢接和铰接框架,习惯叫法框架是指钢接的,铰接时则称为铰接框架。


7.住宅钢结构常用的结构体系是:钢架(纯框架)、框架-支撑,框架-剪力墙。



1 frame structure and frame shear wall are the most common. They are both a dual lateral force system.

In the seismic zone, the dual lateral force system is required. It is not suitable to use hinged frame and support (or shear wall). In the non seismic zone, the hinged frame can be used to support or shear wall. It is very important in the earthquake zone. The performance of concrete shear walls is not as good as the supporting frame.


2 housing both to bear the vertical load, but also to bear the level of force. Bearing vertical load by beam, column, bearing level by lateral force component.


3 pure frame system is the most simple, it has good ductility, seismic performance is the best (the 26 layer of the Hotel New Otani Chang Fu Gong on the use of pure framework). Its disadvantages are steel more. But especially more bays in two directions of multi-storey buildings, pure steel frame is not much. This system is used in most of the steel structures in the 60 m in Japan.


4 high-rise building structure is characterized by the structure of the horizontal displacement control, structural design is mainly to the horizontal displacement is not more than the control value.


5 in the steel structure housing, there are three main anti lateral force structure: steel frame, supporting frame, shear wall.


6 the "frame" here refers to the frame of the joint steel. Strictly speaking, framework consists of a steel joint and hinged frame, used names framework is refers to the steel, the hinging said hinged frame.


7 commonly used steel structure residential structure system is: steel frame (frame), braced frame, frame shear wall.
