When the steel arch ring of a steel tube arch,which has large span and diameter,being lofted in fabrication,the preset camber of individual cross section for the arch ring under stressless condition must be considered.

Multi-objective anti-seismic game design of arch ring structure;

Anti-seismic optimization of arch rings for raising dynamic stability of arch dam;

Topology optimization and rationality of results for arch rings

Mountain reinforced masonry arch example of the engineering background of the original masonry arch set up under the Arch.

The 3-D finite element model is used to have simulation calculation on arched aqueduct for west channel in Dalong irrigated area over Ningyuan River.

By analyzing arches with different bevel and bearing length based on FEM,with a 4m-span erose-arch as example,the paper found that the effect of different bevel and bearing length to the arches to be in the similar rule and the effect of different bevel go identically when bearing length is close to the out diameter of the arch.

A steel arch is set up in order to static and dynamic analysis of the structure with different load cases by SAP2000.

Circular steel arches are distributed along the short span of the shell as the main load-bearing component,while steel tubes of rectangular section are distributed as purlins between the arches along the long span.

Construction technology with support of the long span main arch ring of the reinforced concrete arch bridge;

Demolishing scheme of main arch ring in deck-type reinforced concrete trussed arch bridge;

For the old road widening and rebuilding discussion is made on the design and the construction technology of stone arch bridge especially in its foundation, main arch ring, roadway pavement, sidewall and fills.

According to the method of determining the safe thickness of arch ring which is reinforced by adding a new arch ring,this paper proposes a method for determining the thickness of inner arch ring under the arch bridge.
