Study on Effect of Wind Load and Earthquake Load on Multi-storey RC Framed Buildings

Now a day the increase in the construction of tall buildings, residential and commercial sector, and the new trend are towards taller and slender structures. Though the effect of wind and earthquake, forces becoming important for every structural designer to know. Every engineer is facing with the problem of providing stability, strength for loads like lateral loads. That’s the reason wind as well as earthquake loading have become the influential factors in tall buildings. Loads that are lateral loads play important role for drift. The drift must be taken into consideration for tall structure. The above mentioned are some of the key issues which affect the behavior of structure and economy of the building. This thesis focuses the effects of lateral loads on medium and tall buildings the storey forces, displacements, storey shear, story drift every part of are analyzed on every level of height on the building, Indian codal provision gives us the basic wind speed at 10m height for some important cities/towns. However it does not provide for all the cities in India. In the following work attempt is made to find the effect of lateral loads i.e. wind load and earth quake loads for various models having shear walls and without shear wall. For the study a symmetrical building plan is used with 16 storeys and 31 storeys are analyzed and designed by using structure analysis software tool ETABS-2013. The study also includes the determination of base shear, displacement, storey drift, storey forces and the results are compared with them. These parameters have also considers the effect of shear wall. In order to design a structure to resist wind and earthquake loads, the forces on the structure must be specified.
