中文摘要 台灣地區由於人口結構不同於其他國家,因此建築物常使用多量的磚牆或鋼筋混凝土牆作為隔間之用,但由於主體建物之側向勁度和強度較牆為弱,而這些具有較多牆體之建築的耐震行為可能由牆決定,因此,若能在不佔空間的情形下,以補強方式有效地提高牆的抗震能力,使其承擔大部分之地震力,即可減少梁柱構件受地震破壞之情形發生。 本研究主要是以不佔空間之條狀複合材料版(如FRP複合材料)進行磚牆之補強,試驗牆體分為1B及B/2磚牆厚度厚等型式,將這些牆體以條狀複合材料版補強後,進行反覆載重試驗,並與未補強之牆體型式的試驗結果進行分析,除可以了解其耐震能力及破壞模式,研究含牆之非韌性構架的耐震行為,亦可探討本計劃所提補強方式之可行性,並建立相關實驗數據,作為日後分析含牆構架行為模擬之依據。 最後,將以上所建立的非線性分析模式應用至二層二跨之含牆構架作為實例探討。
ABSTRACT For the conventional RC buildings in Taiwan, brick walls or RC walls are frequently used for some purposes. However, the effects of the walls in terms of mechanics properties on the behavior of the buildings are not considered in the design. Researches on the analysis of buildings with brick walls or RC walls have shown that the walls do have significant effects on the behavior of the buildings, especially for the in-plane motion. The investigation of the damaged buildings in Chi-Chi Earthquake did show this fact. Consequently, strengthening the walls in some ways can be a good way to enhance the seismic resistance of buildings. In this present, the main purpose is to study the applicability of strips of composite plate on strengthening a brick wall surrounded by a non-ductile RC frame by experiments. In the proposed testing program, two types of walls will be constructed, namely, brick walls with 1B and B/2 thick. These walls will be strengthened by two strips of composite plate installed along diagonals, and tested under a cyclic loading. The experimental results in terms of stiffness, strength, ductility, and failure pattern will be compared with those without strengthening obtained in other sub-projects. These experimental results will be valuable in understanding the behavior of a non-ductile frame having wall with and without strengthening, which will also be applied to theoretical analysis in the next stage as a comparison basis. Finally, an appropriate nonlinear material model provided in the program will be found by matching the analytical results with the experimental results for plane frame with wall. Then, the obtained model will applied to analyze a multi-story and multi-bay structure with walls.
