【摘要】：以實施屋頂綠化的一個三層框架結構房屋和一個五層框架結構房屋為例,并結合其他二層和四層的工程實例,按照房屋總層數(shù)不同和增加的綠化荷載的大小,分別對結構進行了整體抗震性能分析。通過對增加綠化荷載前后結構周期、樓層地震剪力、框架柱軸壓比以及框架柱和框架梁配筋的變化等比較分析,論證是否需對欲進行屋頂綠化的房屋進行結構整體的抗震驗算。
[Abstract]:Taking a three-story frame structure house and a five-story frame structure house for example, and combining with other engineering examples of two and four stories, according to the difference of the total floor number of the building and the size of the increased greening load, The seismic behavior of the whole structure is analyzed respectively. Based on the comparative analysis of the structural cycle before and after the increase of the green load, the seismic shear force of the floor, the axial compression ratio of the frame column and the change of the reinforcement of the frame column and the frame beam, it is proved whether it is necessary to carry out the seismic checking calculation of the whole structure of the building which wants to carry out the roof greening.
