APPENDIX B, FALSEWORK REMINDER LISTB-4APRIL 2020Design LoadsB-4.01Vertical Design Loads: Minimum vertical design load (dead load plus live load) on any falseworkmember is 100 psf. This includes supports for a construction walkway extendingbeyond edge of deck or for bent cap falsework. For stress analysis, the design dead load is the weight of concrete, forms,reinforcing steel and falsework members. For deflection, the design dead load is the weight of concrete only, i.e. withoutforms and rebar dead weight. Design live load includes the following:o 20-psf over the total area supported by the member under consideration.o 75-plf at edge of deck overhang acting over a maximum length 20-feet. Doesnot need to be applied simultaneously with Bidwell on deck overhangbrackets.o Weight of equipment (finishing machine, etc.) applied as a concentrated loadat point of contact.B-4.02 Horizontal Design Load:The assumed horizontal load is the greater of the following:o Sum of the actual loads due to equipment, construction sequence or othercauses and wind loading.o 2% of the total supported dead load of the bridge during the unloaded andloaded condition.B-4.03Miscellaneous Loads: Increased vertical design load adjacent to roadway and railroad. Increased vertical load due to load redistribution caused by prestressing forces. Horizontal load caused by stream flow pressure. See Caltrans Trenching &Shoring Manual for hydrodynamic forces. Loads due to vertical and horizontal components of cable loads.B-5Shop DrawingsThe items in this list should be shown on the shop drawings.
