Abstract
A Study on Structural Performance of Non-Prismatic Girders with Double Corrugated Stiffened Steel and Composite Webs - written by Saranya Radhakrishnan M , Binu P published on 2020/07/06 download full article with reference data and citations
Highlights
Bridge girders with corrugated webs have a number of advantages such as more out- of plane stiffness, higher buckling resistance and shear capacity, excellent strength and web stability than that of conventional flat web girders
Numerical modelling of three types of Single Non -prismatic girders were performed – (1) Single Non-prismatic Girder with Double Corrugated Web (No additional stiffeners or no additional material is provided with corrugated web portion of girder), (2) Single Non – prismatic Girder with Double Corrugated Stiffened Steel Web (Here stiffeners are provided in between two Corrugated webs), (3) Single Non prismatic Girders with Double Corrugated Composite Webs (An additional material Ultra- Lightweight Cement Composite (ULCC) fill is provided along with two corrugated webs)
The following conclusions are derived from this present paper:. For both Single and Dual girders, the load carrying capacity and strength of Non - prismatic girders with Double corrugated steel webs are affected by tapered ratios of corrugated web
Summary
Bridge girders with corrugated webs have a number of advantages such as more out- of plane stiffness, higher buckling resistance and shear capacity, excellent strength and web stability than that of conventional flat web girders. Some examples of bridges provided with corrugated steel web girders are the Maupré Bridge constructed in France and the Hondani Bridge constructed in Japan. Large forces generated on the girders result in buckling of single corrugated steel webs. For improving its strength and web stability, Double corrugated webs can be provided. The present study focuses on Double corrugated web girders. The purpose of this paper is to obtain numerical modelling results on Single and Dual linearly tapered girders (Nonprismatic girders) with Double corrugated webs. In this paper the effect of Flat Flanges (FF), Hollow flanges (HF) and Composite flanges (CF) on the performance of Non prismatic girder with Double Corrugated Composite Webs (DCCWG) was investigated
