Determining the pattern of lateral displacement distribution in the height of structures and the factors affecting it, has an important role in increasing the accuracy of optimal design and functional design against various seismic loads. In this paper, the pattern of lateral displacement distribution between floors at the height of flexural reinforced concrete frames is investigated and the effect of seismic intensity and pulse period on this issue is investigated. The studied frames are three structures of 3, 9 and 15 floors of RC Moment-resisting frames. the middle frames of the structures were non-linearly modeled in 2D in the SeismoStruct 2021 program, and nonlinear analysis was performed under the set of records and at different seismic intensities. the displacement response of the structures was compared. The results showed that in orderly short-term reinforced concrete bending frames without any irregularity under the set of selected accelerometers in this research, the effect of all records is almost equal and displacement occurs in the upper floors. As the height of the structures increases and the effect of higher modes increases, the effect of the pulse period of stagnation and seismic intensity is felt. |
