调平法在建筑结构设计中的应用研究

Application of Leveling Method in Building Structure Design

由于建筑功能使用要求,各种大跨度及高层建筑在现代建筑设计中越来越常见。建筑平面及高度的多样性,使得该类建筑的竖向构件在重力荷载作用下会产生差异变形,由此导致结构附加内力增大,不利于结构承受水平荷载。为减少这种由于差异变形导致附加内力增加的不利,在结构设计过程中,可通过调平法来降低附加内力。本文通过举例某办公楼工程的梁柱节点内力分析,发现了相邻柱差异变形所产生的附加内力会影响梁端弯矩的特点。进而采用调平原理,可以在结构设计过程中方便找到竖向构件变形趋势,从而进行变形协调调整,使受力更合理。

Due to building function requirements, a variety of large-span and high-rise buildings in modem architectural design is increasingly common.Building plan and height diversity makes the vertical elements of such building under gravity loads will produce differential deformation, resulting structure additional internal forces increased, the structure is not conducive to withstand horizontal loads.To reduce this deformation leads to additional internal forces due to differences in the adverse increase in the structural design process, additional internal forces can be reduced by leveling method.By way of example of a beam-column joints of internal forces building engineering analysis we found additional internal forces generated by deformation of the adjacent column differences will affect the beam end moment characteristics.Further use leveling principle, you can easily find the vertical component deformation trend in the structural design process, thereby deforming coordinate adjustment, make the force more reasonable.
