［摘要］筆者曾于2006年1月和2007年8月兩次對(duì)西安理工大學(xué)一座12層的框剪結(jié)構(gòu)教學(xué)辦公樓的自振特性進(jìn)行測(cè)試。5·12汶川特大地震中，該樓層2～5的填充墻普遍出現(xiàn)了裂縫。為了考察地震對(duì)該建筑物的影響，于震后又對(duì)其進(jìn)行了相同項(xiàng)目的測(cè)試。地震前、后結(jié)果比較表明：震后縱、橫兩個(gè)水平方向的第一階周期略有延長(zhǎng)，分別延長(zhǎng)了7.62%，3.97%；而縱、橫兩個(gè)方向的第二階周期則有明顯的延長(zhǎng)，分別達(dá)32.62%，36.11%。反映了地震使結(jié)構(gòu)從彎剪型向剪切型變化的趨勢(shì)。

Abstract:Natural vibration characteristics of one 12-storey frame-shear wall teaching and office building have been investigated twice in Xi’an University of Technology in January 2006 and August 2007. During Wenchuan earthquake, there are cracks in the filler wall from 2nd floor to 5th floor of this teaching building. In order to investigate the influence caused by the earthquake, the same test was made after the earthquake. The results of pre-post earthquake showed that there was slight prolongation in longitudinal and transverse direction of first period, which was 7.62% and 3.97% individually, while there was significant prolongation of the one of second period, which reached 32.62% and 36.11% separately. It was reflected that the structure will be changed from shear-bending to shear type by the earthquake.
Keywords:filler wall; frame-shear wall; dynamic characteristics; pulsating method
