[摘要] 為使OpenSees軟件的計(jì)算功能得到充分的發(fā)揮，借助ANSYS平臺(tái)，利用APDL語(yǔ)言編寫(xiě)了ANSYS與OpenSees軟件之間的數(shù)據(jù)接口，利用ANSYS強(qiáng)大的前后處理模塊建立有限元模型并顯示計(jì)算結(jié)果，從而實(shí)現(xiàn)數(shù)值分析的可視化。借助本文編制的數(shù)據(jù)接口程序，針對(duì)某鋼框架結(jié)構(gòu)開(kāi)展了連續(xù)倒塌分析，分析結(jié)果表明：剩余結(jié)構(gòu)的抗倒塌機(jī)制依據(jù)破壞位置的不同而發(fā)生改變；在中柱破壞的工況下，剩余結(jié)構(gòu)具備抗彎?rùn)C(jī)制與懸鏈線機(jī)制提供抗倒塌承載能力；在邊柱破壞的工況下，剩余結(jié)構(gòu)僅依靠抗彎?rùn)C(jī)制提供抗倒塌承載能力。

Abstract: In order to turn OpenSees software to advantage,a new data-interface routine between OpenSees and ANSYS is presented in this paper, using APDL language of ANSYS software, to realize the process of visual modeling and visualization of calculating results. Based on the data-interface routine, an analysis of progressive collapse for planar steel frame structure is camed out. Analytical results show that residual structure has the different resistance mechanism for the different column removal case. In the case of middle column removal, both bending resistance and catenary action resistance become the resistance mechanism of the residual frame structure; on the other hand, only bending resistance could provide resistance capacity of progressive collapse in the case of side column removal.

Keywords: data-interface routine; visual modeling; progressive collapse; resistance mecharusm for collapse
