本文通过制作足尺砌体结构模型并进行拟动力试验研究。试验测得结构在7度罕遇地震作用下地震响应,主要包括结构顶板处、一层圈梁处的位移时程、构造柱根部及梁柱节点处柱纵向钢筋的应变时程。最后绘制并分析结构的恢复力位移滞回曲线,发现结构的刚度和强度虽然有了明显退化,但结构仍保持较好的完整性。
本文通過製作足呎砌體結構模型併進行擬動力試驗研究。試驗測得結構在7度罕遇地震作用下地震響應,主要包括結構頂闆處、一層圈樑處的位移時程、構造柱根部及樑柱節點處柱縱嚮鋼觔的應變時程。最後繪製併分析結構的恢複力位移滯迴麯線,髮現結構的剛度和彊度雖然有瞭明顯退化,但結構仍保持較好的完整性。

Through Ful-scale structure model was designed and fabricated, this paper has experimental study on the pseudo dynamic test. Seismic response of the model under 7 intensity rarely earthquake were measured through the test, it consists the response displacement of structure’s roof and beam-column joint, reinforcement strain of root and beam-column joint. The last, restoring force versus displacement hysteretic curves, the structure stays integrity, although stiffness degaration was obvious with structure strength decreased.
