[摘要]結合重慶瑞安超高層TP2塔樓具體工程,選取典型H型鋼梁與鋼管混凝土柱連接節(jié)點,采用SAP2000軟件進行彈性有限元分析,并采用LSDYNA軟件進行節(jié)點非線性分析,驗證各節(jié)點構造在往復荷載作用下的性能,從而確定大直徑鋼管混凝土柱與鋼梁剛接節(jié)點內部最優(yōu)的構造形式,提高鋼管混凝土柱鋼梁連接節(jié)點的經濟性和施工的便利性。

Abstract:
Based on TP2 tower of the Chongqing Shui On Land high\|rise building, a typical steel H beam\|CFT column connection joint was selected as the study object. An elastic finite element analysis was done by SAP2000. LS\|DYNA program was used for inelastic analysis to validate the performance of the joints under cyclic loading. So that the optimum internal detailing of major\|diameter CFT column\|steel beam rigid joint was obtained to improve economy and convenience of construction.
ords:CFT column; internal stiffening ring; finite element analysis; LSDYNA; SAP2000
