Time history performs analysis which is based on Time-acceleration as an input data which is basically an already experienced acceleration w.r.t time by the ground during seismic event. These analyses methods can be adopted to study the structures having single degree of system or multi degree of freedom system possessingnon-linear characteristics. This paper is mainly focused on behaviour of concrete gravity damwithnonlinear characteristics using seismic time history analysis.In order to study the precise behaviour of structures, seismic time history or response spectrum plays an important role. It’s very important for the dam to survive against seismic vibrations. Concrete gravity dam is a massive structure having many forces acting on it. These structures undergo large deformations in its inelasticregion. Sometimes damages caused by earthquake vibrations are very high that goes beyond repair works.Generally hydraulic structures like concrete gravity dam, canals and RCCmulti-storeyedstructures are sufficiently stiff and ductile. Among these, seismic forces are natural and as we know earthquake is a natural calamity and is so unpredictable.in order to prevent the structure from being collapse, it’s very important to adopt earthquake resistant design philosophy while designing the structure.Waves which arises during Seismic event carriesvery massive speed and when it struck with any structure it travels through foundation to the top roof resulting In-elastic deformation.there may be the possibility of collapse of whole structure or probably it will survive depending upon the design adopted but surely the structure will have some major repairing and strengthening works which will be costly. Gravity dam,time history analysis, dynamic response, vibrations, seismic analysis,SAP 2000.Īny structure that is constructed will undergo many forces such as wind, seismic, self-weight or forces like ice/snow etc. This paper gives a step by step procedure to perform the non-linear time history analysis by using time-acceleration data as input function and then performance of the gravity dam is evaluated with various mode shapes and time-acceleration results Keywords It is an ultimate tool to study the dynamic response of a structure. Time history is basically a method of seismic analysis for the simulation of an earthquake motion. So it is a matter of study to check the behaviour of a dam during and after the application of the loading. Concrete gravity dam is a massive structure which retains a very large amount of water on its upstream side and it is very crucial for a dam to survive against vibrations of earthquake. A concrete gravity dam model is prepared in SAP 2000 to perform the time history analysis. Therefore, dynamic analysis methods forestimating the response of a concrete gravity dam plays an extraordinary role.This paper presents the dynamic non-linear time history analysis of a concrete gravity dam by using CSI SAP 2000. However, these earthquake vibrations are fundamentally dynamic in nature and a static analysis procedure may not be adequate in designing hydraulic structures like Dam. WHO CAN JOIN SAP 2000 TRAININGĪnybody who is interested to learn structural analysis can join the course however mostly civil engineers and structural engineers who want to develop their career in structural analysis and design of buildings.are interested in this course.īasic knowledge of computer and structural design.Dam structures that span navigable waterways are inherently at a risk for seismic vibrations and as such they must be designed to resist these vibrations. Moreover SAP 2000 can be used to calculate the Seismic Weight and self weight of a building easily. In this course we will learn to do the analysis of residential building. Normally SAP 2000 is used for all types of general structures like residential building, stadiums, water tanks, chimneys and so on. SAP 2000 provides structural components which helps to design beam and column of the structure. SAP 2000 has both 2D and 3D features. Learn SAP 2000 at one of the best training center, IT Training Nepal located at Putalisadak, Kathmandu. SAP stands for Structural Analysis Program which is used by Civil Engineers for the analysis and design of structures.
