Energy Analysis And Research For The Plan Frame(Member Model)

The energy-based analysis of earthquake-resistance design can reflect the accumulative damage caused by the continuous time of the earthquake. The transition,conversion and absorb of energy are the basic characters of structural earthquake response. The input energy of earthquake is a relative stable value when the mass and natural vibration period of structure was determined. And the energy-based analysis and design method is definite on its conception and simple in its form. It also can reflect the strength, spectrum character, especially the combined effects of structure damage which coursed by the continuance of strong earthquake. So the energy-based analysis method is paid more and more tension by international earthquake engineering, and it is developing toward practical design method.Researchers in and abroad studied the energy-based analysis method and gained elementary achievements. But there were some committed technical puzzles expected to be solved and completed. So this article researched the drawback of energy-based analysis method and got some conclusions as follows:①The contribution of three element factors of earthquake motion should be considered when selecting the inputted seismic wave in analyzing the structural energy. This paper Comparative Analysis the wave selection with two indexes and The response spectrum area, the wave selection with the response spectrum area of two of the area to complete the two curves similar to the approach in mathematics is unreasonable。It ignored the characteristics of Earthquaking Waves and structures。A earthquaking Wave is fitted Many curves , Its Area deviation is different,So Hysteretic energy of The same structure is different。That leads to Hysteretic energy uncertainty。Thus the wave selection with the response spectrum area with additional other conditions can achieve the scheduled election wave request。②The proportion of hysteretic energy didn't change greatly with the alteration of earthquake excitation on condition that the earthquake waves were accessed by Energy-based selection of earthquake waves. The allocation of hysteretic energy along the interlamination depended on the dynamic characteristics of structures but not the characteristics of earthquake excitation.③Hysteretic energy of Structural framework for the restoration of the two broken line model and the broken line three different models of hysteresis model calculated and Comparative Analysis ,the two broken line Restoring force model has larger zero drift of the phenomenon throug an example。When fully in the development of nonlinear structure。It affects the greatest response characteristics of the statistics, the analysis of Nonlinear structure through the degradation of the two linear analysis of nonlinear structure of the performance is not appropriate In the rare event of earthquake。This paper proposed analytical framework hysteretic energy considers cracking displacement of the three broken line restoring force model。...
