Optimizing The Flexural Behavior of Low-Cost Material Slab Panel Using Coconut Coir Fiber and Rice Husk Ash

Abstract

The steady increase of population density in urban areas of many developing countries like India, from the past decade, has posed a challenge to civil engineers. High-rise buildings serve as workplace accommodations as well as residential buildings. Aesthetic demands of such high-rise buildings are not usually compromised with; Architects in the recent times come up with buildings of irregular shapes which are visually pleasing but can prove to be structurally deficit if they are not designed properly. In the event of an earthquake, these buildings do not respond similar to regularly shaped buildings since the distribution of forces within these structures vary considerably. The lateral displacement of the structures should be carried gradually with the height in order to ensure good seismic performance of the structure which otherwise can cause irrevocable damage. The general approach towards analysis and design of a structure is made under an assumption that the base of the structure is infinitely rigid and consequently restraining the displacements and rotations. Under Seismic loads, the foundations and soil media are subjected to lateral displacements and it influences the superstructure response significantly and imparts redistribution of forces in the structure differing from the forces obtained from fixed base scenario. Hence, the effect of soil-structure interaction has to be addressed and factored into the analysis of a structure. In this thesis, an attempt is made to study the seismic response of an irregular building using E- tabs (V15.2) & SAFE (v12) software. The interoperability of these software facilitates modeling soil-foundation- structure with mutual compatibility. The analysis is performed by equivalent static lad method and response spectrum method as per guidelines of IS- 1893(Part 1): 2002 for Seismic zone V.Slab Panel, Coconut Coir Fiber, Rice Husk Ask, Flexural Behavior
