An innovative lateral force resisting system is investigated that allows steel braced frames to uplift and rock on their foundation, partially isolating the frame. Passive energy dissipation devices are implemented at the uplifting location to control the rocking response to within allowable limits. The structure’s gravitational forces provide an inherent restoring force during the rocking resp...

The present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. Three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. The ductility, over-strength and response modification factors for the...

Aktif deprem bölgelerinde yaygın kullanılan süneklik düzeyi yüksek çelik merkezi çaprazlı çerçeveler (MÇÇ) için güncel Amerikan, Kanada ve Türkiye sismik tasarım yönetmeliklerinde tasvir edilen kapasite tasarımı yaklaşımına göre, MÇÇ’lerdeki kolon kirişler, çaprazların doğrusal olmayan çevrimsel davranışını göz önüne alan, iki farklı yapısal analiz gözetilerek tasarlanmaktadır. Bu hallerinde al...

Background: The special concentrically braced frame (SCBF) is an aseismic structure, but its bracing system exhibits brittle failure and premature buckling connected with the weld fracture of gusset plate post-buckling braces; thus, maximizing role energy dissipation difficult. Methods: Here, this paper proposes a single-story frames ductile casting steel connectors. large inelastic deformation...

A seismic-resistant steel frame with energy-dissipating, chevron-type braces is proposed. The are equipped replaceable hourglass-shaped pins made of duplex stainless steel. Under design seismic loading, energy dissipated through inelastic deformations confined in the while other members remain essentially elastic. As a result, exhibits high post-yield stiffness due to inherent properties stainl...

Background: Different bracing systems of steel Eccentric Braces (EBs) and steel-concrete Buckling-Restrained (BRBs) can be used in frames order to make the stronger resisting lateral loads. These with EBs or BRBs are generally called Eccentrically Braced Frames (EBFs) (BRBFs), respectively. Objective: This study aims investigate having moment link. Methods: The EBFs BRBFs nonlinearly analysed e...
