This study was conducted to the redistribution of internal force and development plastic hinge an MBS with foundations at two different elevations considering torsional effect. The results indicate that base shear is evident embedding ends, story on floors also took place. columns upper- lower-embedding sides, more prominent along slope direction. Consequently, should be considered in practical...

To analyze the multidimensional elastic–plastic response of frame structure with magnetorheological (MR) dampers under strong seismic excitations, test MRD was performed, location matrix in derived, and calculation models without an were established based on three-segment variable stiffness beam. Taking a five-story reinforced concrete (RC) as example, developed by MATLAB software dynamic time ...

In recent years, significant advancements have been made in the definition of innovative “minimal-damage structures,” chasing need for more resilient societies against extreme seismic events. this context, moment resisting frames (MRFs) equipped with self-centering damage-free (SCDF) devices column bases and beam-to-column joints represent a viable solution to improve structural resilience dama...

The present study sought to explore the impact of story maps and audio podcasts as scaffolds on oral proficiency of Iranian EFL learners. The quasi-experimental study was launched with 36 EFL undergraduates in three groups by adopting a counterbalanced 3  3 Latin squared design. All participants were indiscriminately, but in a specified order, exposed to the three treatment conditions of story ...

minimalist story is a kind of very short story that is summarized sometimes in some lines and sometimes in one page. it tells a short event and in addition includes deep contents.studying verses of holy quran we can see stories in different forms and lengths. meanwhile there are some storiesthat are not more than some lines in lengthso it is possible for the researcher to evaluate these stories...

In order to investigate the dynamic response of reinforced concrete spatial frames caused by initial damages, a six-story frame model is analyzed by employing the nonlinear dynamic methodology in accordance with the alternate path method issued by General Services Administration. In this paper, the fiber model and force-based beam-column element are utilized in OpenSees. Four various scenarios ...

This paper presents experimental and numerical investigations on progressive collapse behavior of a two-story glulam frame when the side column is exposed to ISO834 standard fire. The mechanism initiated by fire identified. results show that could be described for three stages, namely bending effect stage, catenary stage failure respectively. These stages are discussed in detail understand stru...

In this paper, necessary and sufficient conditions are stated for the Craig-Sakamoto equation det(I − sA − tB) = det(I − sA)det(I − tB) to hold for all scalars s, t ∈ C. Moreover, spectral properties for matrices A and B that satisfy this equation are investigated.
