The main issue of design and analysis shall consider the excessive deformability induced by the interaction of flexible and kinematic displacement. The space analysis model is enhanced of the Xiang Feng River Bridge using finite element software Midas Civil, whose lower foundation considers the effects of piles and soil. #Analysis and design of three span suspension bridge using midas civil software Analysis of a three span bridge based on theoretical methods and Eurocode 1. Firstly the vibration period, vibration frequency, and modal characteristics are computed, thus the dynamic performance is summarized of the bridge. 3.1.3 Design procedure for mode shapes with constant sign. Then, a proper seismic wave is selected according to engineering conditions and in terms of three orthogonal directions: inputting the adjusted El Centro seismic wave, considering Rayleigh damping, and calculating via the Newmark method. Furthermore, a time-history response analysis under the action of one-dimensional and multidimensional earthquake is performed. Lastly, the results of the response analysis is compared and the behavior characteristics of arch bridge is summarized under seismic action. The results show that the transverse stability problem of bridges is prominent and should be the focus of antiearthquake fortification, the inclined cable tower of this bridge is not conducive to the earthquake resistance of the structure in comparison with the vertical cable tower. #Analysis and design of three span suspension bridge using midas civil softwareĪnd the influence of horizontal and vertical earthquake actions should be considered in antiearthquake designs.
