Providing earthquake resisitant structures with deflected hardened steel and helical springs assembly dampers at foundation level

Abstract

Construction of earthquake resistant structure is a challenging one, newlinebecause of its precious technology with extra-ordinary material requirements. newlineLiteratures relevant to the earthquake resistant structures and dampers were newlinereviewed in broad sense to find out the research gap in formation of newlineearthquake resistant structures. The techniques and vibration control devices newlineused for mitigation of disaster are probably more expensive and highly newlineprecious material and equipment installed. The materials and equipment are newlineentirely different from the materials used in the conventional construction newlinepractice. So there is a gap in research in invention of materials for use of newlineconstruction of earthquake resistant structures. There is no simplicity in newlineprotective measures adopted to enhance the seismic response of structures, newlinethere is a research gap exists. newlineIt is intended to form flexible and restorable structures to withstand newlineseismic forces with sufficient degrees of freedom at base level. This research newlinework presents a basic idea of spring bearing technique at foundation level to newlinesupport the structures like building frames, bridge pillars, water tanks and newlineother structures. A combined spring assembly is fabricated by incorporating a newlineleaf spring assembly with a helical spring assembly. After a brief study on newlinematerials for manufacturing the spring steel, the spring experiments were newlineconducted. The load carrying capacity of individual springs and the two newlineseparate assemblies were found. First one containing leaf springs and another newlineone containing concentric helical spring were used to form a float type newlinefooting and mounted at base level to receive the usual applicable load from newlinethe supports of the super structure. newline newline
