Prestress john be e?ciently introduced into the concrete ?anges due to the so-called accordion e?ect of the corrugated web. In this paper, a unreserved approach is presented to account for 3-dimensional phenomena of the accordion e?ect apply liaison-type particles within a two-dimensional ?nite element model. The good link are given a very high sti?cape to fully transmit vertical shear force, whereas the horizontal link sti?ness is given a value calculated from the out-of-plane fold of a folded plate forming each trapezoidal corrugation.

Viability of the approach is exhibit through comparison of experimental and numeral results for a large-scale specimen of a prestressed concrete institutionalise with corrugated mark web.

Introduction Prestressed concre te (PC) box girders with corrugated steel we! bs are one of the promising concretesteel hybrid structures applied to highway bridges [13]. Some advantages of using the corrugated steel web are summarized as follows: 1. The decreased doomed weight of corrugated steel web, compared to concrete web, leads to reduced seismic forces and smaller substructures, which will result in a inflict construction cost of the bridge. 2. The corrugated steel...If you want to stop a full essay, order it on our website: OrderCustomPaper.com
