Seismic Performance Assessment and Probabilistic Repair Cost Analysis of Precast Concrete Cladding Systems for Multistory Buildings
Recent probabilistic evaluations have shown that the repair costs for typical multistory buildings after minor and moderate earthquakes are heavily influenced by the amount of nonstructural damage. However, most of the efforts in nonlinear dynamic modeling focus on representing the behavior of structural elements and do not include the effects of nonstructural elements. An important nonstructural element is the exterior cladding system. Analytical models of three typical precast concrete cladding designs attached to the nine-story SAC building are created in OpenSees. The effect of the cladding system on the response of the bare moment frame is studied through modal analyses, nonlinear static pushover analyses, and dynamic time-history analyses. Structural reliability analyses are performed on the most vulnerable components to identify the sensitive design parameters. Finally, the damage states of the cladding components are identified from experimental data and analytical models. The damage models show that the cladding systems can become significantly damaged even in a low-level earthquake. The analytical models, along with repair quantities and unit repair costs obtained from industry experts, are used to calculate the distribution of the total post-earthquake repair costs of the cladding systems following the Pacific Earthquake Engineering Research Centers (PEER) Performance-Based Earthquake Engineering (PBEE) methodology.
