Discussion on construction quality influences on structural seismic performance

According to seismic damage investigation analysis,against to the construction quality problems existing in major structure beam and column joint,prefabricated floor,wall and stairways,the construction quality influences on structural seismic performance were discussed.The Wenchuan earthquake damage indicated that the damage degree of same type structure was different,the better construction quality structure always can reach large earthquake no collapse design goal under strong earthquake effect.
