BONETT Ingeniería structural walls reinforced concrete buildings Displacement Based Design Method displacement ductility demand and capacity In displacementbased design methods some demand considerations, starting from the first mode of vibration, are usually made. However, some authors have called the attention on the importance of taking the higher modes into account, due to their influence in the distribution and demand of both, moments and shears along the vertical elements, with significant effects. In this work, the method presented allows to consider, in a practical way, the effect of the higher modes on the seismic response of a structure. The proposal to achieve it, is asimplified model of Three Degree ofFredom developed from a mass concentration of four points equally distant along the building height. This method corresponds to an iterative process, in which the analysis and design procedures are carried out simultaneously, thus, avoiding considerations or suppositions on resistance and ductility values. This method has been applied to the structural walls of a 15storey building. The results obtained show theefficiency of the method in terms of the proposed objectives achievement and the fast converging of the iterative process involved. The effect of the higher modes is extremely noticeable in the distribution of shear stresses and the use of an initial predimensioning involving the reinforcement, allows consistency between the analysis and the structural design. 2010 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49615099003 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.163 Vol.77 |
