Seismic Capacity Testing and Model Establishment for the Full-Scale Members of Elementary School and Street-Front Residential Buildings(I)

After the Chi-Chi earthquake, many school buildings were damaged and even collapsed. In this, the safety of school buildings needs to be concerned about. The purpose of this study is to investigate the out-of plane seismic behavior of the partition walls of school buildings. We also used carbon fiber reinforcement polymer to retrofit the partition walls and hope it can improve the seismic capacity of school buildings. In this study we had seven specimens including one pure frame, two frames with 12 cm thickness infilled brick walls(pre-laid and post-laid), two frames with 24 cm thickness infilled brick walls(pre-laid and post-laid) and two frames with CFRP retrofitted 24 cm thickness infilled brick walls(pre-laid and post-laid). In laboratory the out-of-plane double-curvature cyclic tests were carried out to simulate the full-scale school partition wall frames in the earthquake. In the test the out-of-plane strength provided by brick walls was not significant but vertical load support provided by brick walls was important to provide residual strength for the frames. About the retrofitted specimens, the better strength was as prediction. The maximum strength and residual strength of the retrofitted specimens were better than the un-retrofitted ones.
