000015609 520__ $$2eng$$aResearch in the past few years has indicated that code designed eccentric buildings exhibit ductility demands under strong earthquake motions that are unevenly distributed throughout the structure. More specifically, it is found that elements at the so called “flexible” sides of the buildings exhibit substantially higher ductility demands than elements at the so called “stiff” sides. Such an uneven distribution indicates suboptimal material use and a potential for premature failure of certain members. In the present paper this problem is demonstrated for two L-shaped five story buildings, a torsionally stiff and a torsionally flexible. Subsequently a simple procedure is used to modify the original design that exhibits a substantially improved behavior in terms of ductility demand distribution. The results are quite promising and could be the basis for improving current codes.
