钢结构住宅设计中的节点和支撑构造要求发布时间：2015-11-2 10:00:29 浏览次数:506
1 when supporting the steel tube concrete connection, the joint shall not be welded on the wall of the tube wall, and the tube wall is opened.
2 joint design should comply with seismic code and "high steel specification" requirements.
3.12 layer below could not be located in the basement, but at the moment, the calculation of column base reaction force to increase, strictly speaking, to do under large earthquake of the reaction and does not destroy. 6, 7 degree area allowed the use of column foot, but 8 degrees and above should be used when the embedded column base. Not allowed to use the hinged column.
4 flange groove full penetration welds, require the use of a weld to ensure the welding quality. Some standard provisions of the pressure vessel to use a grade weld. This is a misunderstanding. The pressure vessel is very important, beam flange and column connection is also very important, can not use two.
When the 5.7 layer is above, the frame beam column should be rigid connected in the frame support system.
6 should not be filled in the steel tube supporting concrete, the earthquake resistance.
It is a good method that the 7 column can be directly connected with the beam column by the small cantilever and the beam is connected with the beam. At this point, the use of beam splicing flange welded joints, but also the use of full - Section bolt connection. In the above splicing, the bending moment of the web is considered.
8 beam and the rigid connection of the steel pipe concrete column, and now with the addition of the rib and the inner diaphragm, are all right. However, we should pay attention to the thickness of the tube wall and the plate or the ring plate.
