Test study on bending-resistance of precast shell for RC beam in fabricated integral structure with precast shell and cast-in-place core concrete

ZHI Zhengdong1,ZHANG Dachang2,LU Zhongqiang3(1.College of Civil Engineering,Yancheng Institute of Technology,Yancheng 224051,China;2.College of Civil Engineering,Nanjing University of Technology,Nanjing 210009,China;3.Jiangsu Provincial Architectural Design and Research Institute,Nanjing 210029,China)  
A new type fabricated integral structure with precast shell and cast-in-place core concrete is introduced in this paper.Tests on bending-resistance of concrete U-shaped shell are carried out,and these failure modes,cracking load,ultimate bearing capacity are investigated.Besides,the calculating method of cracking strength is provided.The results can be referred for engineering application.
