The theme of this paper is interaction between and within plate-based roof structures braced by branching columns and tensile members. Interaction of cross-laminated timber plate structures and branching column systems have been investigated in a previous paper [1] by utilising physical models and Genetic Algorithms. Based on this study the concept of interaction and the utilisation of compress...

Although concentrically braced frame (CBF) systems enjoy high elastic stiffness and lateral strength, they show a low seismic energy absorption capacity. This dilemma is due to the buckling of CBFs’ diagonal members under compressive loading. To overcome shortcoming, researchers have proposed use dampers improve behavior CBF systems. Among dampers, metallic shear damper most popular thanks its ...

In this paper, an adaptable and architecturally flexible lateral stiffening system for tall timber buildings between 50 147 m is developed investigated. The based on a tube-in-tube concept. internal tube consists of braced core, the external frame structure with semi-rigid beam-column joints in façade. Based finite element framework, more than 500 000 simulations different configurations are ca...

This paper suggested a new connection protocol, adding cover-plate between shear links and column, which was used to enhance moment and shear carrying capacity of beam, relax the restriction and assure the sufficiency development of plastic deformation of the link, and dissipate more earthquake energy. Considering the scale ratio of 1:3, the experimental data was achieved by a specimen under cy...

In this study, the methodology recommended by FEMA P695 is employed to evaluate seismic performance of self-centered y-shaped (SCY) braced frames. To apply system interest, twenty archetype models are deigned. The collapse safety then evaluated through incremental dynamic analyses (IDA) and pushover analyses. results show that secondary stiffness length self-centering (SC) element key parameter...
