摘要

A bridge using strut and tie member is provided to control the droop of girder and design the section of the girder. A bridge(100) using strut and tie member comprises a support girder(110) extended and installed to the throttling direction at the upper part of support and having the height corresponding to the support bending portion moment, a central part girder(120) which is connected between the support girders and formed into the height smaller than the height of the support girder while it is bent with central part, having the height corresponding to the positive moment, a strut member(140) which is between the support girder and support girder and installed in upward and downward is included from the central part girder lower-part between the tie member.
