What are the suitable reinforcement methods for collapsing parts in houses? When the width of the window wall is too small or the seismic resistance can not meet the requirements, the reinforced concrete window frame can be added or reinforced with steel mesh mortar surface layer, slab wall and so on. The masonry column, composite column, reinforced concrete column or reinforced with steel mesh mortar surface layer and slab wall can be added when the seismic resistance of the wall segment supporting the beam can not meet the requirements. The design and construction of composite columns can be carried out according to rules 9.3.3 and 9.3.4 of this code.
When the wall supporting the cantilevered member does not meet the requirements of judgment, it is advisable to add reinforced concrete columns or masonry composite columns at the end of the cantilevered member to strengthen, and to check the cantilevered member. If the partition wall has no tie or is not firmly tied, it can be strengthened by edge setting, embedded steel jacket, anchor bar or steel tie bar; when the partition wall is too long or too high, it can be strengthened by steel mesh mortar surface layer.
When the staircases, elevators and water tanks out of the roof do not meet the judgment requirements, the surface layer or additional columns can be used to reinforce the roof. The upper part should be firmly connected with the roof components, and the lower part should be connected with the reinforcement method of the main structure. When a chimney, a parapet wall without tie, a door face, etc. beyond the regular height, it is advisable to remove, reduce the height or use section steel, steel rod reinforcement. When the anchorage length of the cantilevered member does not meet the requirements, it is possible to add a pull rod or adopt a way to reduce the length of the cantilever.
