从异形柱框架的受力特点出发,引入相当轴惯性矩的概念,依据斜弯曲理论,推导了异形柱的抗弯刚度和抗侧移刚度的计算公式,为异形柱框架的简化计算提供了理论依据。
The concept of equivalent moment of inertia is introduced based on the force characteristics of special-shaped column frame. Based on oblique bending theory, the formulas for calculating the flexural rigidity and lateral stiffness of special-shaped columns are deduced, which provides a theoretical basis for the simplified calculation of special-shaped column frames in accordance with.
