LOADING TABLES (HD)Service LoadsThe load tables provide load/deflection criteria for most common applications. These tablesprovide a concise reference allowing the specifying authority to select the appropriate bearingbar size and spacing for the intended application.Pedestrian loads are commonly analyzed with uniform and concentrated loads. Forpedestrian comfort, deflection is typically limited to 1/4".Heavy duty and vehicular load tables are presented for specific load conditions. Heavy dutyload tables are presented with deflection limited to the lesser of 1/8" or L/400.For more detailed information, see Loading Table.Anping Enzar Metal Products Co., comENZAR METAL1
