Prestress set up be e?ciently introduced into the concrete ?anges due to the so-called accordion e?ect of the corrugated web. In this paper, a dewy-eyed approach is presented to account for 3-dimensional phenomena of the accordion e?ect exploitation tie-up-type pieces within a two-dimensional ?nite element model. The good link up are given a very high sti? ness to fully transmit vertical shear force, whereas the horizontal link sti?ness is given a value calculated from the out-of-plane refraction of a folded plate forming each trapezoidal corrugation. Viability of the approach is show through comparison of experimental and numeral results for a large specimen of a prestressed concrete institutionalise with corrugated mark web.

Introduction Prestressed concrete (PC) box girders with corrugated steel webs 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 out of work weight of corrugated steel web, compared to concrete web, leads to reduced unstable forces and smaller substructur es, which will result in a put down constr! uction cost of the bridge. 2. The corrugated steel...If you want to stop a full essay, order it on our website: OrderCustomPaper.com
