摘要
为研究集中载荷作用下四边固接矩形薄板的刚度,将矩形弹性薄板等效成双向正交板条,以板条宽与板宽的比和载荷作用位置为参数,研究板的长宽比与板刚度的关系。以实际工程中常见的剪力墙尺寸为例,给出计算板刚度的拟合公式,并进行有限元验证,证明拟合公式误差较小。
To study the stiffness of rectangular thin plates with four edges fixed,the rectangular elastic thin plate is equivalent to a two-way orthogonal strips.Taking the strip width to plate width ratio and load action position as parameters,the relationship between length-width ratio and plate stiffness is studied.Taking the common shear wall size in practical engineering as examples,the fitting formula for calculating plate stiffness is given.The fitting formula is verified by finite element,and the error of the fitting formula is small.
