Torsional Behavior Study of Reinforced Concrete Boxingsection Members Subjected to Biaxial Eccentric Compression，Shear and Reversed Torque/Liu Jiming1，Shi Qingxuan2，Li Zhijun2，Liang Lin3，Yu Maohong1（1 Xi’an Jiaotong University，Xian 710049，China；2 Xian University of Architecture and Techology，Xian 710055，China；3 Qingdao Technological University，Qingdao 266033，China）
Abstract:The nonlinear behaviors of the RC boxingsection columns under combined torque are discussed，including hysteretic curve，cracking torque，initial stiffness，failure type，ductility and carrying capacity.The research results are helpful to deduce the strength and stiffness formula of the test members and to establish design clause for the RC design code.It verifies the assumption of space changing angle truss theory and discusses the application in engineering based on the test results.
Keywords:RC boxingsection member； combined torque； torsional behavior
