Technology of Seismic Detailed Evaluation and Seismic Retrofit--Development of TEASPA 4.0

The Taiwan Earthquake Assessment for Structures by Pushover Analysis (TEASPA), developed by NCREE, has now been updated to V4.0. This new version will still use P-M hinges on columns (which is the same as V3.1). V4.0 improves simulated methods for members and methods of seismic retrofit as researched by NCREE. In addition, V4.0 has added standard and evaluation methods of interim seismic retrofit into a handbook to assist with the prevention of collapse by soft and weak floors in mid-to-high-rise buildings. NCREE cooperated with Sinotech while developing V4.0 (which is different to previous versions) to develop a web-system for TEAPSA users. In this new version, users can upload models to the website to set nonlinear hinges and evaluate seismic capacity. NCREE will collect the uploaded structural information for future research.
