a large number of bridges and buildings that are currently used, are made of slabs with opening. some of these buildings and bridges have been severely damaged because of natural disasters such as earthquake, storm and other effects such as materials fatigue and alkaline and corrosive agents. therefore, retrofitting and strengthening of these structures is essential and affordable. in this rese...

Lightweight steel-framed (LSF) construction, given its advantages, has the potential to reach high standards in energy and environmental performance of buildings, such as nearly zero-energy buildings (nZEB). When compared with traditional construction, LSF system offers distinct benefits in such fields as sustainability, cost-effectiveness, constructive process, and safety at work. Despite the ...

Michel BRUNEAU Director, Multidisciplinary Center for Earthquake Engineering Research Professor, Department of Civil Engineering University at Buffalo Buffalo, NY 14261 [email protected] Michel Bruneau is conducting research on the seismic evaluation and retrofit of existing steel bridges, steel buildings, and masonry buildings. He has published over 200 technical publications as a result of ...

A new structural control system using damper-installed shear walls in lower stories with reduced stiffness is proposed for vibration control of high-rise RC buildings. That system has some design variables, i.e., height of shear wall, degree of stiffness reduction at lower stories, and quantity of dampers. In this paper, some parametric studies on the shearbeammodel with a stiff beam against tw...

This study aims at assessing the use of a novel damper, which is called Prestressed LEad Damper with Straight Shaft (or PS-LED), for seismic rehabilitation RC framed buildings. device provides high energy dissipation by friction activated between lead core and shaft achieves specific output force preloading during assembly. In order to show effectiveness PS-LED retrofit existing buildings, stru...

Passive energy damper systems have been considered as efficient and practical method to improve seismic behaviour of structures under lateral loads including seismic. In this study, a new passive steel damping system with shear mechanism fuse has proposed. Design procedures, recommended equations, parametric analytical studies on novel were provided for strengthening retrofitting purposes reinf...

This study investigates the seismic behavior of deconstructable composite steel/concrete floor systems consisting of precast concrete planks and deconstructable clamping connections attaching the planks to the steel floor beams. The system is proposed to promote sustainable design of composite steel/concrete floor systems in steel buildings via reuse of the structural steel and concrete compone...

A study was conducted for the flexural retrofit of an old apartment house composed a reinforced concrete (RC) shear wall structure. For wall, vertical performed to both ends targeting slender improve performance. The materials were steel plate, epoxy, and non-shrink grout, they connected existing using post-installed chemical anchors. at broken retrofitted as much necessary maintain wall’s leng...

Passive protection systems based on the use of metal shear panels represent an effective way for achieving a significant improvement of the seismic response of buildings. Nevertheless, the dissipative capacity of these devices could be limited by buckling phenomena. In order to reduce the influence of instability, "Buckling Inhibited Shear Panels" have been recently introduced as an innovative ...
