NON-LINEAR RESPONSE OF REINFORCED CONCRETE SPHERICAL DOMES TO AIR BLAST LOADING,

Abstract

A method is developed to predict the response of a concrete dome to an air blast load. The problem is physically non-linear because of the stress-strain laws considered for steel and concrete and also geometrically non-linear because finite displacements are taken into account. The stress-strain relations, and the equations of motion are derived directly in finite difference form for computer use by postulating a lumped mass model to simulate shell behavior. A simplified representation in terms of the model of the behavior of reinforced concrete is also presented. A predictor-corrector method is used to integrate the equations and attention is given to computer efficiency and storage limitations. Finally, some results for the axis-symmetric case are compared to other studies that have been made. (Author)
