REINFORCED-CONCRETE SHELL ELEMENTS SUBJECTED TO BENDING AND MEMBRANE LOADS

Large-scale reinforced concrete shell elements were tested under condi tions of biaxial bending and in-plane normal forces. The details and r esults of the test program are described, and the observed behavior pa tterns are discussed. The test data obtained are analyzed to corrobora te constitutive models currently available for representing the effect s of post-cracking tensile stresses in concrete. The ability of nonlin ear finite element analysis procedures to accurately model shell eleme nt behavior is also examined.
