中文摘要 | 本研究主要探討以矽力康來固定靠牆之儀器櫃或展示櫃時,整體系統所能承受之耐震性能。以矽力康將櫃子固定在牆壁上,除可有效防止櫃子在地震中發生傾倒破壞外,且不會破壞櫃子表面,爲一可兼顧美觀與安全之新型耐震工法。其基本原理爲:將流體狀態的矽力康以類似填角焊接之幾何構造方式,施打於櫃子邊緣與牆壁接觸的交界地方,待其固化後,利用矽力康和牆面材質的黏著力及矽力康本身的強度,達到耐震的效果。爲驗證矽力康之耐震效能,本研究首先進行了靜態側推試驗探討以矽力康固定櫃子系統之耐震能力。實驗結果顯示矽力康材料之耐震強度約與施打長度成正比,在面內與面外方向分別爲8N/cm以及3N/cm,意即其強度由面外方向控制。接著,本研究亦假國家地震工程研究中心之振動台,進行矽力康固定櫃子系統之三軸向AC156設備物耐震反應譜測試。實驗結果顯示,以肢長2cm,兩側各施打長度120cm之矽力康(總長度240cm)來固定質量100kg之櫃子,可保護櫃子通過測試而無任何損壞。其中輸入震波之峰值大小:水平爲1.329、平直爲0.309,滿足台灣建築物耐震設計規範之需求。 |
英文摘要 | In this paper, a non-destructive method for securing wall-supported cabinets against earthquakes is studied, It is found that to glue the cabinet to the wall with similar geometry to fillet welding, in vertical runs on each side of the component and as centered as possible with respect to its center of mass, can reduce the overturning disposition of the cabinet during earthquakes. With this arrangement, the component needs no further restraint at the base. Two series of tests were performed to characterize the performance of the silicone gluing in this study: testing parameters included two types of silicone (common commercial hardware product B&Q and structural product DC-795) and two types of surface finishes (wood veneer and paint-coated steel sheets), while the supporting wall has a normal interior concrete finish. First, static push tests were performed to determine the force-displacement curve of silicone gluing in two principal loading directions. The joint capacity was found to be directly proportional to the installation lengths of the silicone runs, which strengths of 8N/cm and 3N/cm for in-plane (interface mainly in direct shear) and out-of-plane (interface mainly under tensile stresses) cabinet loading directions, respectively; i.e., the out-of-plane loading governed the seismic resistance. Second, the dynamic shake table test was performed to verify the seismic capacity of the silicon-glued cabinet. It showed that the silicone gluing could prevent a cabinet with a 100kg-mass content from overturning under multi-directional excitations compatible with the response spectra prescribed by the ACI 56 non-structural components testing criteria issued by the International Code Council Evaluation Service (ICC-ES), and the intensity of the inputs complied with the seismic requirements of the Taiwanese Building Code. |
