in this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. the designed base was according to provisions of the canadian standard, 2005 nbcc. the behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. these models c...

This paper investigates the seismic performance of two adjacent buildings connected by viscous dampers. Three types damper placement are discussed, including installing dampers within a single building, connecting at same floor level, and inter-story level. Analytical models established to consider various dynamic properties buildings, theoretical solutions obtained, transmissibility curves, ad...

The effect of the vertical component earthquakes on structural behaviour unreinforced masonry (URM) walls is usually not considered by technical codes for ordinary buildings. Recent scientific literature, however, indicates that earthquake may play a significant role in crack pattern URM and their collapse. This paper investigates seismic capacity damage scenario two-story regular wall, describ...

After the catastrophic destruction of October 2005 Kashmir earthquake, first building code Pakistan was developed in 2007. The sole purpose (BCP) to incorporate advancements earthquake-resistant design fortify structures and ensure safety citizens against future seismic events. 2007, BCP not revised till 2021 include changes over time. However, recently updated version highlights that seismicit...

Design of blast resistant structures is an important subject in structural engineering, attracting the attention of governments, researchers, and engineers. Thus, given the benefits of optimization in engineering, development and assessment of optimization methods for optimum design of structures against blast is of great importance. In this research, multi-objective optimization of steel momen...

To study the design method of sectional area and initial tension of wire rope brace of the prestressed braced steel moment frame structure system, theoretical analysis of this structure system is conducted in this paper. The lateral stiffness formula is derived. It reveals the lateral stiffness is related to the lateral stiffness of bare steel moment frame, story height, the distance between co...

Earthquake events have shown that besides the earthquake forces, interaction between fault rupture and structures could cause a lot of damage. Field observations revealed need to design for fault-induced loading in regions with active faults. In this study, three-dimensional numerical simulation was carried out evaluate performance 20-story frame building subjected propagation normal rupture. A...
