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...

We screened a tomato (Lycopersicon esculentum L.) cDNA library (1.3 x 106 plaque-forming units [7]) with a polymerase chain reaction fragment that was thought to be a specific probe for a shikimate dehydrogenase, and we isolated 11 independent clones (Table I). The cDNA inserts were subcloned into pSK+ (Stratagene) and sequenced from the 3' end. All 11 clones contained the same sequence, and th...

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...

Concentrically braced frames and eccentrically braced frames are efficient seismic resistant systems but they are generally prone to develop storey collapse mechanisms. As underlined in some previous papers with regard to eccentrically braced frames, this tendency depends on the overstrength factors and damage distribution capacity factors resulting from the use of common design procedures. In ...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...
