Prestress grass be e?ciently introduced into the concrete ?anges due to the so-called accordion e?ect of the corrugated web. In this paper, a impartial approach is presented to account for 3-dimensional phenomena of the accordion e?ect using railroad tie-type fractions within a two-dimensional ?nite element model. The good golf links are g iven 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 twist of a folded plate forming each trapezoidal corrugation.

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

Introduction Prestressed concret e (PC) box girders with corrugated steel web! s 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 beat(p) weight of corrugated steel web, compared to concrete web, leads to reduced seismal forces and smaller substructures, which will result in a disdain construction cost of the bridge. 2. The corrugated steel...If you want to stop a full essay, order it on our website: OrderCustomPaper.com
