This paper deals with the topology optimization of strut-and-tie models in non-flexural reinforced concrete members by using the Evolutionary Structural Optimization (ESO) method for plane stress continuum structures with displacement constraints. By means of systematically removing elements that have less contribution to the stiffness from the discritized concrete member, the actual load paths...

To reduce the thickness of reinforced concrete foundation members used in construction and structural applications, a previous study developed tested strut–tie retrofit system installed foundations. This proposes optimum details steel-tie for with reduced via finite element simulation-based load-bearing capacity assessment. The parameters (structural steel type, plate thickness, number strut fr...

Abstract In this study, a novel type of loading strut device is presented, which introduced in portal frame external prestressing reinforcement and used to constitute cable-supported structural system. The was found be capable elongating by rotating the middle screw applying prestress steel strand new simulated analyzed using ANSYS finite element analysis software. Moreover, it for test practic...

ABSTRACT In this paper, seismic analyses are performed of a reinforced concrete frame building with participating masonry walls carried out. The spectral method the Brazilian code – ABNT 15421:2006 was used to obtain lateral loads. equivalent diagonal-strut model employed simulate axial stiffness in frames, according different formulations founded literature. main purpose is evaluate difference...

in this research, the steady-state flow filed around a 3d body and rotor configuration of the robin helicopter is simulated. the rotor is modeled by an actuator disk. for this purpose, an annular computational domain replaces the rotor and some modeled source terms are added to the momentum equations. this modeling of rotor considerably speed up computational time. the flow field over this heli...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

This paper presents the influence of strut and tower on aerodynamic force blade for vertical axis wind turbine (VAWT). It has been known that struts degrade performance VAWTs due to inherent drag losses. In this study, three-dimensional Reynolds-averaged Navier–Stokes simulations have conducted investigate effect flow pattern around rotor region, distribution, performance. A comparison made thr...
