Y形支撑耗能环有限元分析

在钢结构当中,可通过添加耗能支撑的做法来提高结构的抗震性能.经验表明,耗能支撑在实际工程当中的作用仍然存疑.近年来的研究发现在Y形耗能支撑端部添加钢环(耗能环)能明显改善系统的抗震性能.本文基于已有试验结果,利用有限元软件ANSYS对钢环的参与作用进行了参数分析,包括连接板长度以及钢环厚度,分析结果显示,增加连接板长度...

Parameter finite element analysis of Y-shaped energy dissipating ring

The dissipating bracings are always used to enhance the seismic performance of steel structures,but previous earthquakes has risen doubts about using this member.Recent research show that the energy steel rings can be used to improve the seismic performance of the system.Based on the existed test results,parameter analysis is conducted with the software ANSYS,and the influence of plate length and thickness and ring thickness are analyzed,the results show that,when increasing the plate length,the load capacity grows,and the stress in the middle increases,when increasing the ring thickness,the capacity and energy dissipation increases obviously,but stress intensity decreases.
