Abstract
Abstract null null The National Center for Research on Earthquake Engineering (NCREE) in Taiwan has implemented the static pushover procedures for the detailed seismic evaluation of school buildings. In the pushover analysis, the hinge properties of columns, beams, brick walls and RC walls are carefully calibrated based on the full scale experiments conducted in NCREE in the past ten years. Additionally, auxiliary modules for calculating the hinge properties have been developed by NCREE researchers to enhance user friendliness. This could allow engineers to more accurately apply available commercial software. However, when the auxiliary modules are applied to commercial software, the user must first define then assign the sections to the corresponding columns, beams, brick and RC walls in the text-based files. Without the graphic user interface, errors have commonly been found in cross-platform operations. The Platform of Inelastic Structural Analysis for 3D systems (PISA3D) has been developed since 2002 in NCREE. PISA3D provides a friendly user interface and high computational efficiency for engineers and researchers to simulate the nonlinear systems under various kinds of load effects. In order to resolve these issues noted above in the application to commercial software, NCREE has customized the nonlinear structural analysis program, PISA4SB (Platform for Inelastic Structural Analysis of School Buildings) specifically for the school building structures. PISA4SB allows the user to conveniently construct the analytical models for typical low-rise school buildings. After the gravity load analysis is conducted, PISA4SB automatically incorporates the column axial loads in calculating the parameters for the multilinear fracture material properties of any plastic hinge. PISA4SB evaluates the capacity curve and computes the seismic performance point based on the given design response spectrum provided by the user for the school building site. Engineers can conveniently apply PISA4SB to complete the seismic evaluation of a school building without cross-platform operations. The detailed development and example applications of PISA4SB are illustrated in this paper.
