近幾年來,鋼結構在國內外之工程建設上被大量廣泛地採用,使得鋼與混凝土之混合設計日趨頻繁,而隨著科技的進步,各項精密儀器或高級設備與結構物之連接亦與日俱增,更突顯了各類型接合設計之重要性,錨栓由於強度大且適用性廣,因此成為工程上常被採用的連接物之一。本研究主要利用有限元素分析方法探討化學黏著錨栓在靜態及動態荷重下之行為,除了預估錨栓系統的極限承載力外,並藉由混凝土裂縫之生成與裂縫之形式,搭配黏著劑與鋼錨界面的剪應力分佈情況,來判斷錨栓系統的破壞模式。此外配合有限元素分析之所需,亦進行了材料性質試驗以及一組錨栓拉拔試驗。所建立的有限元素分析模型,經與靜態試驗結果比較後發現預估的極限承載力相當準確,而破壞模式的判斷也與試驗結果大致吻合。在動態分析方面,探討的變因包括埋置深度、錨栓尺寸、荷重反覆次數、反覆荷重大小、以及混凝土抗壓強度等五項,由分析結果發現當錨栓受反覆荷重作用時,錨栓的埋置深度愈深或錨栓尺寸愈大時,錨栓所能承受的總反覆荷重次數愈多,而混凝土強度較高時,雖亦能增加錨栓承受荷重的反覆次數,但影響並不顯著。
Since steel structures are increasingly used in all kinds of construction, the study of steel-to-concrete anchorage becomes an important task for both the engineers and researchers. The major objective of this research is to study the behavior of chemically adhesive anchors under static and dynamic loading. Ultimate capacity and failure mode of anchors system are to be predicted by finite element analysis. Material tests and a set of anchor pull-out tests are also performed in order to determine the correct material properties for finite element analysis as well as to provide extra data for evaluating analysis model. By comparing the analysis results with some experimental results verifies that the developed analysis model can predict the anchor behavior to an acceptable degree. Among various influential factors, embedment length of anchor, anchor size, concrete strength, and loading cycle are selected to investigate for the dynamic analysis. It is shown by the analysis results that deeper embedment length or larger anchor diameter both increase the loading cycle of an anchor system. However, higher concrete strength makes very slight improvement on the overall capacity of anchor system.
