Seismic design concept from a pseudo - static test of steel reinforced concrete frame - core wall structure model with transfer floor 核心筒结构模型拟静力试验对抗震设计的启示
Such work have been done as follows : 1 . the pseudo - static tests of three 1 / 2 - scale models r . c . frames with special - shaped columns have been conducted ( 2 )对异形柱框架结构的侧向刚度和水平承载力的计算方法进行了分析研究。
The paper probed the applying of multi - ribbed slab with outer light frame structure ( mrsolfs ) to the upper structure of buildings with commodious space at the bottom and the feasibility of replacing lfswsums with frame - supported multi - ribbed composite slab structure ( fsmrcss ) . firstly , the paper carried out test study base on the pseudo - static test under horizontal loads on four two - spanned model members of fsmrcss , including three 1 / 2 - scaled two - storeyed models and one 1 / 3 - scaled three - storeyed model . by the test study , the paper analyzed the test results , including analysis on mechanical property of the constructure under vertical loads , and failure mode , deformation capacity , aseismic performance under horizontal loads and constant vertical loads 本文首先对三个两跨两层和一个两跨三层的底部大空间框支密肋复合墙结构的1 2和1 3比例模型进行伪静力试验研究,通过对底部大空间框支密肋复合墙结构在竖向荷载及与水平低周反复荷载共同作用下的受力性能的试验研究,探讨了结构的变形性能、滞回耗能和破坏形态,并与框支砌体结构进行对比分析。
Based on the experimental data , this paper uses the ansys program to do nonlinear finite element analysis . by analyzing the two walls with nonlinear finite element method , this paper gets keleton - frame curves of the two walls . by comparing the data of the fem and pseudo - static test , the result show that load - deflection plots for specimens from the fem is agree with the experimental data 采用通用有限元分析软件ansys5 . 7 ,对带缝空心剪力墙板进行了非线性有限元分析,得出了此类新型构件在单调加载下的破坏模式、骨架曲线、破坏特征点和单调荷载下的刚度退化规律,并与试验研究结果对比分析。
The traditional shear wall structure has such disadvantage as large self - weight , stiflhess and seismic forces , poor - ductility and energy saving . based on the post investigation , this paper put forward a new type of hollow shear wall structure with seams . the seismic behavior and design method are investigated and following work on test and theory are done : based on the pseudo - static test of two hollow shear walls with seams , the seismic behavior of the walls are researched 针对其抗震性能和设计方法,作了较为系统的试验研究和理论分析:以多层住宅结构底层抗震墙为原型,完成了两片带缝空心剪力墙板的1 2模型低周反复加载试验,对这一新型构件的抗震性能进行了系统研究。
