In this way, you can apply different load factors to Erection Load 1(CS) and Erection Load 1(CS) from dead load (CS). I opened your model file and found that the 'Barrier' and 'Wearing Surface & Utility' load cases are separately defined as 'Erection Load 1' and 'Erection Load 2' respectively.Īfter analysis, CS: Erection Load 1 and CS: Erection Load 2 are generated. It seems that you already know my answer. How do I separate the DC Construction Stage Loads from the DW Construction Stage Loads to properly define the load combinations? Among the various options provided by the Load Combination function, the Auto Generation option creates load combinations that satisfy the desired design standards of the user. However, some of these are DC loads (deck, girder, etc.), and others are DW loads (wearing surface and utilities), and therefore need different load factors. In the Load Combination function, the user can combine several load cases used in structural analysis. On the Load Combinations screen, all of the different dead loads (deck, self-weight, wearing surface, utilities, etc.) are lumped together under one load case called Dead Load (CS). The user manual says that all loads that are to be considered in the Construction Stage Analysis have to have a Load Type of "Construction Stage Load (CS)". WIthin the model, I have construction staging defined. ![]() ![]() I have a model of a bridge created using the Steel Composite Bridge Wizard.
