ANALYSIS AND DESIGN OF BRIDGE SUPPORT FALSEWORK

Design loads for bridge support falsework are discussed in the context of existing publications. The flexibility of scaffolding connectors is shown to be of importance in the analysis for internal forces of loaded falsework. A simple model of a flexibly-connected bracing model is devised which allows the use of a standard stiffness analysis computer program for this purpose. Methods of approximate analysis are discussed and compared with the results of computer analysis for two example structures, one constructed in A proprietary falsework system, and the other in tube-and-fittings scaffolding. The approximate methods of analysis are further developed for structures with unbraced forkheads and base-jacks. Finally, the effect of approximate methods of analysis on assumed load factors is considered briefly.(a) (TRRL)
