Aij Journal of TECHNOLOGY and Design   22(52) 977-982   2016
Wall-type precast reinforced concrete (WPC) residential buildings using prefabricated concrete panels have maintained high structural quality, although they were constructed more than 40 years ago in Japan. In order to utilize them, seismic behavi...
TAKAGI Jiro, USUI Ryo, NONAKA Toki
Aij Journal of TECHNOLOGY and Design   22(51) 543-548   2016
Significant number of wall-type precast reinforced concrete (WPC) residential buildings exist in Japan, constructed during the 1960-70s.<br>They are assembled using prefabricated concrete panels for the slabs and walls and of high quality in terms...
