Analysis on the Local Stress of the Arch Foot of Tied Arch Bridge with SRC Section Binder
There is no precedent for the application of steel reinforced concrete(SRC)section beams in tied arch bridge,and the stress situation at the arch foot is complex due to the intersection of various components.In order to explore the stress distribution at the arch foot,the finite element software Midas Civil is used to establish a full-bridge model of a tied arch bridge with SRC section binders with a span of 68 m.The most unfavorable load conditions in the construction stage and the operation stage are analyzed,and the corresponding section internal force values are extracted.Then,the ANSYS software is used to establish the local model of the arch foot.By analyzing the local stress distribution law,the most unfavorable position of the steel and concrete structure in the construction and operation stages is pointed out,and the corresponding suggestions are put forward to improve the stress state of the arch foot.At the same time,the stress analysis results reveal the force transmission path of this special bridge type.
