Aseismic behavior of ceramsite concrete T-shaped columns and common concrete T-shaped columns are compared and analyzed. Finally, it′s concluded that low shear-span ratio and low axial pressure and with concealed column or dence stirrup ceramsite concrete T-shaped columns are excelled in aseismic behavior, aseismic behavior of common concrete T-shaped columns is better than ceramsite concrete T-shaped columns.Keywords:ceramsite concrete; T-shaped columns; aseismic behavior; low cyclic loading; experiment作者简介:李守才,硕士,一级注册结构工程师,Email:sdjklsc@163.com。参考文献[1]卫园,等.周期反复荷载作用下L形截面柱试验研究[J].华南理工大学学报,1995,23(3).[2]冯建平,等.L形和T形截面柱的试验研究[J].华南理工大学学报,1995,23(3).[3]徐向东,康谷贻,等.T形截面钢筋混凝土框架柱受剪性能的试验研究[J].工程力学(增刊),1995.[4]曹万林,庞国新,等.钢筋混凝土带暗柱T形柱抗震性能实验研究[J].世界地震工程,1999,15(3).[5]DBJ/T15-15-95广东省标准.钢筋混凝土异形柱设计规程[S],1995.[6]规程编制组.天津市异形柱框轻结构的研究及技术规程编制[J].建筑结构,1999,29(1).[7]CHENG-TZU,THOMAS HSU.T-shaped reinforced concrete members under biaxial bending and axial compression[J].ACI Structural Journal,1989(7-8).[8]郭棣.宽肢异形柱试验研究[D].西安:西安建筑科技大学,2001.[9]李守才,等.陶粒混凝土L形柱抗震性能试验研究[J].世界地震工程,2005(2).
