Dead load of lightweight concrete
WebDetermine the service dead load and liv arrow_forward The floor system of an apartment building consists of 100mm thick reinforced concrete slab (unit weight = 23.6 KN/m^3) resting on three steel floor beams 3.0 meters on centers. Calculate the total dead load in KN/m due to slab for a single floor beam. Assume one-way slab. arrow_forward Webdead load calculation, it is customary to use: • 150 pcf for normal concrete. • The actual value as determined from unit-weight tests for lightweight concrete. Falsework must be designed to support the dead load of the entire superstructure cross section, excluding the weight of the bridge railings during the unloaded and loaded stages.
