GENERAL Loads and deflections are theoretical and based on static loading. Note: Spans to the right of heavy line not recommended. Deflections shown 16-51 SPACING loadings. For lesser design loads 13-102 SPACING based on tabulated reduce deflection in direct proportion. For serrated surface increase depth by one size.

For serrated surface, increase depth by 7mm for load rate. GENERAL Loads and deflections are theoretical and based on static loading. Note: Spans to the right of heavy line not recommended. Deflections shown based on tabulated loadings. For lesser design loads reduce deflection in direct proportion. For serrated surface increase depth by one size.
