ABSTRACT
Recently there has been a considerable increase in the number of tall buildings, both residential and commercial, and the modern trend is towards taller and more slender structures. Thus the effects of lateral loads like winds loads, earthquake forces are attaining increasing importance and almost every designer is faced with the problem of providing adequate strength and stability against lateral loads. For this reason in recent years wind and earthquake loading have become determining factors in high-rise building design. This lateral loads are mainly responsible for drift. So the design of tall structures must take into consideration of the drift. Although there are no specific requirements in the effects of drift, it is an important issue which may significantly impact the buildings structural behavior and economy. This paper aims to analyze the drift for lateral loads and comparison on drift for earthquake and wind loads on tall structures. To analyze the drift, we used programming with C (version C++ 4.5). Mainly we analyzed three types of high rise structures such as rigid frame , couple shear wall and wall frame structures. Strength, serviceability and stability in tall structures have to include in design criteria. Strength is satisfied by limit stresses, while serviceability is satisfied by drift limits in the range of H/500 to H/I000.On the other hand stability is satisfied by sufficient factor of safety against buckling and P-Delta effects.
