In Wenchuan e arthquake , infilled frame stru cture severely injured, especially there are c racks , collapse damage or other damages in infilled wall s. In fact, p resent study often considers the infilled wall sas non -ponents, and in Chinese n orm the basic period of infilled frame structure is multiplied by the reduction factor of to to take into account the impact of infilled wall , in essence, it is still calculated in accordance with pure frame structure, so this method is not reasonable. Based on various typical damage s in Wenchuan earthquake , the thesis a naly s es t
