Experimental Verification of Wave Vibration Analysis of a Classical Multi-story Multi-bay Planar Steel Frame

چکیده

Wave vibration analysis approach is found a systematic and concise approach in solving complex vibration problems in built-up frame structures. From the wave vibration standpoint, vibrations propagate along a uniform waveguide, and are reflected and transmitted at discontinuities. In this study, a multi-story multi-bay steel frame is built. The wave vibration analysis approach is applied to study coupled bending and axial vibration in the planar frame. The analytical results are verified through real time vibration tests on the multi-story multi-bay steel frame. Comparisons are made between the analytical and experimental results. ________________________________________________________________________________

OPTIMIZATION OF STEEL MOMENT FRAME BY A PROPOSED EVOLUTIONARY ALGORITHM

This paper presents an improved multi-objective evolutionary algorithm (IMOEA) for the design of planar steel frames. By considering constraints as a new objective function, single objective optimization problems turned to multi objective optimization problems. To increase efficiency of IMOEA different Crossover and Mutation are employed. Also to avoid local optima dynamic interference of mutat...

Evaluation of Free Vibration Characteristics of Steel Space Frames

ABSTRACT:The design of structures subjected to natural hazards such as earthquakes and typhoons demands safety of structures which is governed by the natural frequencies and the amount of damping in each mode of vibration. Fundamental frequency of a building and its damping have a remarkable effect on the magnitude of its response. The ability to predict these characteristics at the design stag...

Free Vibration Analysis of a Sloping-frame: Closed-form Solution versus Finite Element Solution and Modification of the Characteristic Matrices (TECHNICAL NOTE)

This article deals with the free vibration analysis and determination of the seismic parameters of a sloping-frame which consists of three members; a horizontal, a vertical, and an inclined member. The both ends of the frame are clamped, and the members are rigidly connected at joint points. The individual members of the frame are assumed to be governed by the transverse vibration theory of an ...

Effect of Steel Confinement on Behavior of Reinforced Concrete Frame

The strength and ductility of concrete improve under multi-axial compressive stress due to confinement effect. Some parameters are effective for considering the confinement in concrete and various stress-strain models were developed by different researchers. Longitudinal and transverse reinforcement steels can influence on confinement in reinforced concrete members. In this paper, various stres...
