conventional methods for seismic design of structures are based on building capacity. because of the disadvantages of conventional methods, base isolation system  is known as an effective solution to protect structures against earthquakes. in this study the operation of 2-storey steel frame with and without seismic isolators under near-fault earthquake of chichi، northridge and  capemendocine  ...

Dynamic analysis of a four legged offshore truss structure under the effect of wave forces is conducted in this study. The structure is a three-storey space frame system formed of cylindrical members whose legs are supported by lateral bracings and vertical diagonals. The structure and its environment are numerically modelled by the finite elements method with the fluid-structure interaction. D...

in this paper, based in the l ukasiewicz logic, the definition offuzzifying soft neighborhood structure and fuzzifying soft continuity areintroduced. also, the fuzzifying soft proximity spaces which are ageneralizations of the classical soft proximity spaces are given. severaltheorems on classical soft proximities are special cases of the theorems weprove in this paper.

The improvements in (3D) three–dimensional underlying examination and processing assets have permitted the effective safe plan of taller constructions. These constructions are outcome expanding metropolitan densification financial suitability. pattern towards continuously has requested a move from conventional strength based approach structures to an emphasis on obliging general movement design...

The significance of incorporating soil-structure interaction effect in the analysis and design of RC frame buildings is increasingly recognized but still not penetrated to the grass root level owing to various complexities involved. It is well established fact that the soil-structure interaction effect considerably influence the design of multi-storey buildings subjected to lateral seismic load...

Multi-storey steel buildings are usually designed with rigid connections between beams and columns or simple hinged a stiffening system. The paper focuses on the 3D structural design of multi-storey including floor slabs shear walls. method numerical modelling has been applied to investigate influence certain elements lateral stiffness building structure, when walls considered in design. Four h...

Nine full-scale light-framed wood construction (LFWC) specimens were tested cyclically to study the effect of the upper storey and the vertical load on the performance of wall framed shear wall (WFSW) in the first storey. Results showed that the effects of the upper storey with the vertical load on the performance of WFSW were to: (1) increase the elastic stiffness, (2) reduce the ultimate defl...

In structural analysis, the base of structures is usually assumed to be completely rigid. However, the combination of foundation and the subsurface soil, makes in fact a flexible-base for the soil-structure system. It is well-known that the structural responses can be significantly affected by incorporating the Soil-structure Interaction (SSI) effects. The aim of the present study is to provide...
