The seismic performance of elliptic braced moment resisting frame (ELBRF) is assessed here and is found that the structural behavior is improved and is of free of architectural space. The demand for seismic performance of ELBRF is estimated through conventional pushover methods of 3, 5, 7, and 10-story ELBRF frames and they are compared with special moment resisting frames (SMRF) and X-Braced C...

In the last two decades, high-rise timber buildings have been built using glulam truss system, even with limited openings. Moment-resisting frames (MRTF) semi-rigid beam-to-column connections can be an architecture-friendly way to provide a load-carrying system vertical and horizontal loads for buildings. these structures, of adequate ductility are crucial ensure robustness energy dissipation. ...

the objective of this paper is to determine the drift demand hazard curves of steel moment-resisting frames with different number of stories in territory of tehran this is done through the combination of the results obtained from probabilistic seismic hazard analysis and the demand estimated through the best probabilistic seismic demand models. to select the best demand model, in this paper, a ...

Traditional truss design and analysis assumes pinned joints at the connections. Other design provisions recommend that the trusses be designed and analyzed as frame structures, with careful consideration of the stress, timber behavior, and joint response. A large body of knowledge has been compiled detailing truss behavior as it relates to member properties and responses. However, the modeling ...

In this research, using the Modified Compression Field Theory (MCFT), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. The proposed model includes a nonlinear shear spring, an axial spring, two inclined truss member...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...
