the present study assesses the seismic performance of steel moment resisting frames (smfs) retrofitted with different bracing systems. two structural configurations were utilized: ordinary concentrically braces (ocbfs), buckling-restrained braces (brbfs). a 7-story and 18-story steel perimeter smfs were designed with insufficient lateral stiffness to satisfy code drift limitations in high seism...
The paper reports an investigation into the forging of solid powder circular disc with large slenderness ratio, between two flat dies. The deformation pattern during the operation is influenced by many factors, which interact with each other in a complex manner. The decisive factors are the interfacial conditions, initial relative density of the preform and the geometry of the preform. An attem...
In this study, experimental study on six RC columns with different slenderness ratios under axial rapid loading was conducted to investigate the axial compression behaviour of RC columns considering the effect of strain rates. The failure pattern of the specimens and the relations of axial loading versus the axial deformation were described. From the test results, the specimens under static and...
In the paper, air cavity created by vertical water entry of cylinders with different slenderness ratio (defined as “s=L/D”) is investigated experimentally, theoretically, and computationally. The study focused on range Froude numbers, Fr = V /( gr ) 0.5, (12< Fr< 30). Particular attention given to effect ratios surface seal time, evolution process cavities. To understand physical processe...
this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...
