在臺灣一般住宅建築物中,基於生活隱私與外界區隔的要求,通常會使用混凝土填充牆設置外牆或室內隔間,此牆體雖為非結構桿件但仍具有極高的側向勁度與強度,於地震力作用下為最先受損之關鍵構材,故須了解震後損傷牆體之殘餘耐震性能。
本研究以臺灣建物常用之混凝土填充牆為試驗參考,設計最小配筋量之填充牆含柱構架,分別實施靜態循環加載試驗以及動態加載後再進行靜力循環加載之試驗,比較純靜態試驗與受動態加載試驗下牆體損傷之趨勢,以驗證靜態試驗加載結果的合理性,接著參考日本建築防災協會構件損傷度判定基準,搭配試體損傷表徵與殘餘裂縫寬度建立牆構件損傷度準則,提出牆構件於各損傷度之勁度折減係數,探討牆構件震損後之變形性能;本研究亦參考耐震詳細評估法建議之鋼筋混凝土牆構件之非線性預測模型,先以試驗結果與預測模型進行比較與修正,再依震後損傷度對應之殘留勁度,提出震損後牆構件之修正模型,作為工程師於實務應用時之參考。最後彙整過去牆構件試驗資料,依各試驗結果整理建議牆構件各破壞模式下之震損程度判定基準,定義各試體損傷程度與相對變位角,進行統計回歸各破壞模式下損傷程度趨勢,以利後續針對震損折減因子進行修正。
In general residential buildings in Taiwan. Based on the requirements of privacy and outdoor partitions, RC infill walls are usually used as exterior walls or indoor partitions. Although this wall is a non-structural member, it still has extremely high stiffness and Strength. It is the key structural material that is the first to be damaged under the action of an earthquake, so it is necessary to understand the residual seismic performance of the damaged wall after the earthquake.
This test refers to the design of the minimum reinforcement ratio of the concrete infill wall commonly used in buildings in Taiwan. Perform a static cyclic loading test and a static cyclic loading test after dynamic loading.Compare the trend of wall damage under pure static test and dynamic loading test.Verify the rationality of static test loading results. Then refer to the damage judgment criteria of the Japanese Building Disaster Prevention Association. The damage characterization of the specimen and the width of the residual crack are used to establish the damage criterion of the wall member. Propose the stiffness reduction factor for each damage degree of the infill wall. Discuss the deformation performance of the wall member after earthquake damage. Then use the nonlinear prediction model of the RC wall structure recommended by the detailed evaluation of Taiwan earthquake resistance. First compare and modify the test results with the prediction model. According to the residual stiffness corresponding to the damage degree, propose a modified model of the wall structure after earthquake damage. As a reference for engineers in practical application. Finally, summarize the past wall component test data. Sort out the test results and suggest the criteria for determining the degree of earthquake damage under each failure mode of the wall structure. Define the damage degree and deformention of each test body. Statistics return the trend of the damage degree under each failure mode. In order to facilitate the subsequent correction of the earthquake damage reduction factor .
