Construction errors and their case studies

Apr 06,2016 for welded structure sa36 bridge performance#0183;The bridge was designed as a single continuous box girder of welded steel.17.4/6/2016 VIT University,Chennai Campus 17 Investigation of collapse showed that the collapse was due to the buckling of the diaphragm at the support (i.e.,at the root of the second span being erected).Design for steel bridge construction - SteelConstructionfoHow the bridge is designed and how it is built are linked.Ensuring that this link is recognised will have an effect on the safety and quality of the construction.Methods of erecting steel bridge structures vary considerably from site to site and from project to project.The subject of erection aspects is therefore a wide and varied subject.
