Abstract: A finite element model is verified accurate enough to simulate the static test of one reinforced-concrete frame with specially shaped columns subjected to the loss of a ground corner column. As the frame sustained loads primarily depending on the beam resisting mechanism in the test, four related parameters, namely the height of beam section, rebar ratio of beam, rebar ratio of slab a...

Progressive collapse starts when any load-carrying elements of the building during extreme loading, such as earthquakes, blasts, or fire. The Precast Steel Reinforced Concrete (PSRC) buildings comprise precast RCC columns and steel girders. These structural are connected to form a moment-resisting frame susceptible progressive collapse. However, this system has advantage inherent stiffness damp...

in this paper, the optimal location and characteristics of tadas dampers in moment resisting steel structures, considering the application of minimum number of tadas dampers in a building as an objective function and the restriction for destruction of main members is studied. genetic algorithm in first generation randomly produces different chromosomes representing unique tadas dampers distribu...

Wind and earthquake disasters in the world often cause billions of dollars of damage to buildings, most of which is to non-engineered buildings-especially homes. Wood-frame homes use connectors which exhibit partial rotational rigidity at the member ends, making analytical solutions difficult. This is due to the lack of information about the complex behavior of the connections used in this type...

In moment resisting reinforced concrete framed buildings, corner joints are found at the roof level. These joints, if designed for gravity loads and are based on pre-seismic codes, may suffer substantial damage during earthquakes particularly under opening cycles, i.e. those causing flexural tension on the inside of the joint. Several techniques of repair and strengthening of reinforced concret...

This paper presents the seismic performance of moment-resisting timber frame (MRTF). In Japanese urban areas, there are many small houses, and it is difficult to design a wooden building ensure both comfortable plan that effectively makes use constrained sites, also lacks flexibility in design. Therefore, expectations rising for high MRTF using residential members. this study, clarify dynamic b...

Steel plate shear walls (SPSWs) have advantages such as high elastic stiffness, stable hysteresis behavior, energy absorption capacity, and decent ductility. However, one of the main drawbacks SPSWs is their buckling under lateral loading. To address this issue, a simple practical solution in form using trapezoidal moment connection (PMC) narrow gap between infill columns presented. The PMC wil...
