The purpose of this paper is to study the behavior of semi-rigid frames under near-field earthquake records. Three moment resisting frames of 3, 6 and 12 stories were designed according to UBC97 provisions. The design was carried out for rigid and semi-rigid connections with and without considering the near-field coefficients. For semi-rigid frames, the connections were designed as top and seat bolted angle connections with double web angles (TSAW). Near-field and far-field earthquake records were applied to the rigid and semi-rigid frames and the results of nonlinear dynamic analysis showed that in the case of rigid frames, beams and even columns yielded under near-field records and the connections fractured. But in the case of semi-rigid frames, connections have less strength compared to those of columns and beams. The connections absorbed the earthquake energy by proper rotations and in this manner, stress in beams and columns decreased. It was concluded that the use of semi-rigid frames with slight strength designed by considering the near-field coefficients can be suitable for near-field regions. It should be noted that the lateral drift should be controlled in these frames.
