To serve its purpose a structure must be safe against collapse and serviceable in use. Serviceability requires that deflections be adequately small to keep the cracks within tolerable limits. Although the widely followed ACI Code suggests a detailed method of deflection calculation, it often cannot exactly perceive the actual behavior of a structure. For this purpose, finite element analysis, u...

From the first commentaries of Akhundzadeh to Jamalzadeh’s introduction to Yeki Bud YekiNabud, i.e., over a period of almost fifty years, we can see a collection of a few scattered commentaries on story and novel which are rarely noticed by researchers. These scattered commentaries can be regarded as the first literary manifests of story and novel. These critiques and commentaries include subje...

Steel plate shear walls (SPSWs) offer good energy dissipation capability when subjected to seismic forces as a robust lateral load resisting structure. This research investigated the cyclic behaviors of innovative infill web-strips (IWS-SPSW) and conventional unstiffened steel (USPSW) experimentally numerically. As result, two specimens 1:3 scale three-story single-bay IWS-SPSW USPSW were fabri...

This paper tells the story of Vectorwise, a high-performance analytical database system, from multiple perspectives: its history from academic project to commercial product, the evolution of its technical architecture, customer reactions to the product and its future research and development roadmap. One take-away from this story is that the novelty in Vectorwise is much more than just column-s...

A beam-column element based on the Euler-Bernoulli beam theory is researched for nonlinear dynamic analysis of reinforced concrete (RC) structural element. Stiffness matrix of this element is obtained by using rigidity method. A solution technique that included nonlinear dynamic substructure procedure is developed for dynamic analyses of RC frames. A predicted-corrected form of the Bossak-α met...

This paper presents the influence of gravity framing on collapse risk steel frame buildings with perimeter special moment frames (SMFs) designed in Turkey. For this, four- and eight-story have been considering related current specifications codes. Header end-plate connections are used for beam-to-column joints system. A nonlinear analytical model that simulates hysteretic behavior header is cal...

In this study, the relationship between the viewing of television programs (programs toward God, the lessons of the Quran, the Fath) in the fields of Tehran citizens to moral values (Faith, virtue, purification and self-purification, prayer, reading culture, integrity, justice-oriented, good relations with others) have been investigated. The statistical population of this research over 15 years...

plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...
