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作者簡介:李守才,碩士,一級注冊結構工程師,Email:sdjklsc@163.com。參考文獻[1]衛(wèi)園,等.周期反復荷載作用下L形截面柱試驗研究[J].華南理工大學學報,1995,23(3).[2]馮建平,等.L形和T形截面柱的試驗研究[J].華南理工大學學報,1995,23(3).[3]徐向東,康谷貽,等.T形截面鋼筋混凝土框架柱受剪性能的試驗研究[J].工程力學(增刊),1995.[4]曹萬林,龐國新,等.鋼筋混凝土帶暗柱T形柱抗震性能實驗研究[J].世界地震工程,1999,15(3).[5]DBJ/T15-15-95廣東省標準.鋼筋混凝土異形柱設計規(guī)程[S],1995.[6]規(guī)程編制組.天津市異形柱框輕結構的研究及技術規(guī)程編制[J].建筑結構,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.寬肢異形柱試驗研究[D].西安:西安建筑科技大學,2001.[9]李守才,等.陶粒混凝土L形柱抗震性能試驗研究[J].世界地震工程,2005(2).
