摘要:
现行国家规范中规定的现浇板厚度较大,湿作业太多,这不仅容易造成材料的浪费,拖延工期,而且使结构自身由于自重较大,刚度也随之增加。在地震力作用下,容易造成结构自身的地震作用力大,结构的自振频率加快,自振周期减小等不利因素。所以基于现行国家抗震规范,对现浇楼板和装配式空心楼板在8度罕遇地震作用下的性能进行了研究分析。通过对比现浇板和装配板的结构位移、层间位移角等分析,得出:装配式结构的整体刚度与现浇整体式的结构的刚度接近,基本符合国家现行抗震规范的要求。
Abstract:
As the prescriptive cast-in-place slabs in the existing national codes are in great thickness and involve too much wet operations, so this will not only cause material waste and time limit delay of project but also increase stiffness of the structure accordingly due to the greater weight of the structure itself. Under the action of seismic forces, the structure is susceptible to unfavorable factors like great seismic forces, increased natural frequencies of the structure and decreased natural vibration period of the structure. So the performance of the cast-in-place floor and fabricated hollow floor under earthquakes of different levels were studied and analyzed based on the current national seismic code. Analysis was made by comparing the displacement and inter-storey drift angle of the two kinds for structure. It is concluded that the overall stiffness of the prefabricated structure is close to that of the cast-in-place integral structure, which is basicly line with the requirements in the current national seismic code.
