Study on the Erection of Steel Girders - 'JSP-53W'

We will conduct an examination and verification of the cross-section of the steel girder erection method and the buckling of the web plates.

The steel girder launching construction study "JSP-53W" automatically calculates the sectional forces for the entire process of the launching construction method using a hand-launching machine for steel box girders and plate girders, based on the Steel Structure Erection Design Guidelines (2012, Japan Society of Civil Engineers). It also conducts checks and evaluations for buckling of sections and web plates. The buckling checks for web plates are based on the Road Bridge Design Specifications and Commentary I Common Edition, II Steel Bridges and Steel Members Edition, DASt Richtlinie 012 Stability Checks for Steel Plates (October 1978, West German Steel Structure Committee), and the Steel Structure Erection Design and Construction Guidelines (2012 edition, Japan Society of Civil Engineers).
