Estimation of Load-Induced Damage and Repair Cost in Post-Tensioned Concrete Rocking Walls
《Journal of Shanghai Jiaotong university(Science)》2018年第1期122-131,共10页JAFARI Abouzar DUGNANI Roberto 
Post-tensioned concrete rocking walls might be used to avoid severe seismic damage at the base of structural walls, decrease residual drift, and lessen post-earthquake repair costs. The prediction of load-induced dama...
