Internal Force of Double-Column Pier Coping and Prestress Tendon

Zhao Jun,Xiang Zhongfu,Jiang Yu (School of Civil Engineering & Architecture,Chongqing Jiaotong University,Chongqing 400074,China)  
The finite element of double-column coping was analyzed by MIDAS.The influence of coping height,pier spacing,and pier height on the control section internal forces of coping was compared separately,so as to provide the basis for the reasonable prestress tendon distribution under different forces of coping.Through engineering examples,the correct selection of structure calculation model lays the foundation for the number and location of prestress tendon.The analysis shows that when the distance of the pier is fixed,copping beam height has little influence on internal force;while the copping beam height is fixed,the distance of the pier has tremendous influence on internal force of the copping beam,the bending moment in the middle span increases with the pier distance,but it goes opposite in the fulcrum of copping beam.With the pier height goes down,the bending moment has the tendency of increasing in the midspan and reducing in the fulcrum.
