TSUNAMI RESISTANT DESIGN (TRD)

Abstract

Presently no authentic guidelines are available for TRD and it is very urgent requirement to draft new code for tsunami load. Here is an initiation to guide for designing of superstructure in the tsunami prone areas. This paper is also a helpful document for drafting a code and giving guidelines for Tsunami Resistant Design. Paper describes a new concept to draft a code on Tsunami. This paper is giving guidelines only on Tsunami Resistant superstructure Design. After giving present availability of code guidelines on tsunami in the beginning, some important forces for tsunami like Drag force (Hydrodynamic force), Buoyant force, Impact force, Surge force and Hydrostatic force are discussed with their detail primary equation explanations. After designing any building, it is equally important to made stability check for that design. Stability checks for overturning, sliding, compression (crushing) and tension are also explained with their basic equation explanations. Apart from it some important design guidelines, specifically for tsunami prone areas, are also given with figures for clear understanding. Application of this paper, guidelines for soil condition and sub structure design, can also be made. Again application can also be extended up to formation of complete design process for Tsunami Resistant Design and proposal for drafting a code on Tsunami. Paper is an extension in the initiated effort by an author of this paper to guide for Tsunami Resistance from Civil Engineering point of view.
