整体式内隔墙对框架抗震性能影响的研究

RESEARCH ON THE INFLUENCE OF INTEGRAL INNER PARTITION WALL ON SEISMIC BEHAVIOR OF FRAME

近年来的震害研究表明,填充墙在地震作用下易遭受破坏,并会直接影响到整体结构的抗震性能,在当前建筑工业化的背景下,内隔墙板的整体高效安装、柔性连接显得尤为重要&针对某一实际工程,提出了一种先装轻质整体式内隔墙板及其柔性连接节点,并通过ABAQUS软件模拟研究其在多遇地震、设防烈度地震及罕遇地震情况下,墙板与框架梁柱之间的缝隙宽度,柔性连接节点中钢筋的间距、直径、锚固深度等对混凝土框架结构抗震性能的影响&结果表明:墙板与框架梁柱之间的缝隙使得框架结构在多遇地震和罕遇地震下的受力形态发生较大改变,钢筋间距、钢筋直径、钢筋锚固深度均不同程度地影响整体框架结构抗震性能,但并不影响结构的最终破坏形态.

In reccni years the seismic damage reseerch shows that the infill wall is vulnerabie to damage undes the action of earthquake,which directly affects the seismic behavior of the overall structuse.In the cursent background of ccnstruction industrialization,the overall efficient installation and flexible ccnnection of the innes partition wall panel is particularly important.Foe a practical project,the papes proposed a lightweight integrated integral partition wall panel and itr flexible jointr,and studied the influencc of the gap width betteen the plate and the frame beam-column and spacing,diameteaand anchoaingdepth oesteelbaasin eleiibleeointson theseismicbehaeioaoeconcaeteeaame structures undes frequent earthquakes,fortification earthquakes and rare earthquakes through the simulation analysis of ABAQUS software.The resultr showed that the stress pattern of frame structure changed greatly undee frequent earthquakes and rare earthquakes because of the gap betfeen the plate and the frame beam-cclumn.The spacing,the diametee and the anchoring depth of the steel bars affected the overall frame structural seismic behavioe,but did not affect the final failure mode of the structure.
