Abstract:Finally, a framework is proposed for evaluation of structural redundancy against incipient collapse limit state. In this framework: (1) the maximum column drift ratio (MCDR) or biaxial spectral acceleration (BSA) is used to measure both demand and capacity of a given building; (2) the demand and capacity analyses of a building are performed, from which the probabilistic demand curves and the distribution of capacity are constructed; (3) both aleatory and epistemic uncertainties in demand and capacity are taken into account; (4) based on the results of (2), a uniform-risk redundancy factor, RR, for design to achieve a uniform reliability level for buildings of different redundancies is obtained. This method is also used to evaluate the redundancy of a given structural system. The rho factors in NEHRP 97 and in NEHRP 2003 and the proposed RR factor are compared and the inadequacies of rho factors are pointed out.
