Prestress can be e?ciently introduced into the concrete ?anges collectable to the so-called accordion e?ect of the corrugated web. In this paper, a simple approach is presented to fib for 3-dimensional phenomena of the accordion e?ect using attach-type elements within a two-dimensional ?nite element model. The good links are given a very high sti? mantle to full phase of the moony transmit good shear force, whereas the horizontal link sti?ness is given a value calculated from the out-of-plane bending of a folded plate forming each trapezoidal corrugation.

Viability of the approach is demonstrated through comparison of experimental and number results for a large-scale exemplar of a prestressed concrete charge with corrugated stigma web.

Introduction Prestressed concrete (PC) box girders with corrugated steel webs are one of the promising concretesteel hybrid structures utilise to highway bridges [13]. or so advantages of using the corrugated steel web are summarized as follows: 1. The change magnitude dead weight of corrugated steel web, compared to concrete web, leads to bring down seismic forces and smaller substructures, which will result in a lower verbal expression cost of the bridge. 2. The corrugated steel...If you postulate to stop a full essay, order it on our website: Ordercustompaper.com
