Characteristics and Related Research of through and Half through Arch Bridges in China

Abstract

As an important transportation infrastructure, some through and half through arch bridges were collapsed at home and abroad. And most accidents were caused by the damage of suspenders. From the structural features, through and half through arch bridges were composed of two parts-upper and lower structure. The upper part of the structure was mainly composed of arch rib, suspender, tie bar, carriageway beam and bridge deck system etc. Research at home and abroad on through and half through arch bridges mainly include: seismic performance, stability, wind vibration, construction, maintenance, suspender tension test, damage identification of the bridges, and so on.
