［摘要］通過一幢20世紀(jì)70年代末建于8度地震設(shè)防區(qū)的砌體填充墻框架結(jié)構(gòu)的模擬地震振動臺試驗(yàn)，得到其破壞形態(tài)與過程，并與有限元分析進(jìn)行對比。利用獲得的較準(zhǔn)確的有限元模型，進(jìn)一步分析純框架結(jié)構(gòu)、設(shè)有砌體填充墻框架結(jié)構(gòu)、設(shè)有鋼筋混凝土填充墻框架結(jié)構(gòu)在不同地震作用下的位移、層間位移角、層剪力等參數(shù)。結(jié)果表明：均勻填充少量砌體墻后，結(jié)構(gòu)動力響應(yīng)與純框架結(jié)構(gòu)較為接近，可在計(jì)算中忽略砌體墻的影響；填充少量鋼筋混凝土墻后，結(jié)構(gòu)自振周期明顯縮短，結(jié)構(gòu)位移響應(yīng)減小，鋼筋混凝土填充墻的影響不可忽略；合理增設(shè)鋼筋混凝土填充墻是框架結(jié)構(gòu)抗震加固有效方法之一。

Abstract:A RC frame with masonry filler walls partly built in the late 1970s (seismic fortification of 8 degree) was taken as the prototype, a series of simulated earthquake shaking table tests were conducted, the failure mode and process of the tested frame were obtained, and the experimental results were analyzed and compared with the numerical ones. Further, the performance of the pure frame structure, frame structure with masonry filler walls and frame structure with reinforced concrete filler walls under different seismic excitations were analyzed based on the accurate finite element model of the structure, and some conclusion were drawn by comparing the response of the structures such as displacment,story drift angle and story shear force and so on. The results show that the dynamic response of the frame with fewer masonry filler walls is similar to the response of the pure frame, the influence of masonry filler wall can be ignored in the caculation; while the effect of the reinforced concrete filler walls cannot be ignored for the reason that the natural vibration period of the frame with reinforced concrete filler walls becomes shorter and the displacement response decreases obviously compared with the pure frame; adding reinforced concrete filler walls is one of the effective seismic strengthening methods.
Keywords:frame structure; masonry filler wall; reinforced concrete filler wall; shaking table test
