Abstract: In multistory reinforced concrete building construction, the freshly placed floor is supported by shores which are supported themselves on several previously cast floors. The construction loads in these supporting floors may appreciably exceed the design service loads. Such loads depend on the sequence of erection and cannot be easily determined. In this report, some methods for determining these erection loads are presented with a few simplifying assumptions. Laboratory experiments were undertaken to determine the variation of the modulus of elasticity and crushing strength of concrete cylinders with age. The variation of flexural strength and stiffness of model reinforced concrete beams with age was also investigated. The shoring loads in a typical flat slab type building were measured and the results are discussed.
