The utilization of passive energy dissipation systems has been created a revolution in the structural engineering industry due to their advantages. Fluid Viscous Damper (FVD) is one of these control systems. It has been used in many different industries, such as the army, aerospace, bridge, and building structures. One of the essential questions about this system is how it can combine with the ...

Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns ~magnitude and distribution! established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7 Standard on the other. The estimated capacities are based on the assumption, verified by numerous sets of calculations, and also used in the ...

seismic retrofit of masonry slabs in existing steel or masonry buildings has found special significance in current codes as failure of unstable jack arch slabs has been reported as a major reason for collapsing structures in middle east deadly earthquakes. in this paper, three retrofit schemes are investigated and compared. the proposed rehabilitation techniques consist of a single x strapping,...

Steel plate shear walls (SPSWs) in buildings are known to be an effective means for resisting lateral forces. By using un-stiffened walls and allowing them to buckle, their energy absorption capacity will increase significantly due to the postbuckling capacity. The post-buckling tension field action of SPSWs can provide substantial strength, stiffness and ductility. This paper presents the Fini...

For the eventual use as regards wave generation and damping, we investigate oscillating contact lines on vertical walls. Stainless steel is used rather than the glass of Ting and Perlin [J. Fluid Mech. 295 (1995) 263] for the vertically sinusoidally oscillating plate over a large range of Reynolds numbers. The non-wetting stainless steel minimizes the static meniscus ignored in our analysis. Ot...

This research concerns the design of an agricultural building with a high degree of sustainability, located in a farm in the south of the Tuscany region, Italy. The building, intended mainly as a wine cellar, offers innovative construction solutions of high deconstructability and has features of low environmental impact, economic competitiveness and constructive simplicity. In particular, the d...

This paper describes the design, testing, and finite element modeling, of a proofof-concept eccentrically braced frame specimen utilizing a hybrid rectangular shear link. The link is self-stabilizing and does not require lateral bracing, making it suitable for use in steel bridge piers where lateral bracing can be difficult to provide (building applications are possible as well). Equations used...
