Fourteen full scale lightweight concrete slabs were tested to provide additional information concerning the resistance of lightweight structural concrete to shear. Since the shear requirements for this type of structure in ACI 318-63 were based on a total of six slab tests, it was considered desirable to supplement this information in order to evaluate or propose modifications to the Code. Slab test results are compared to the shear requirements of ACI 318-63 and to other design approaches that are under consideration as modifications or changes to these requirements.
