钢管混凝土束剪力墙受弯承载力公式推导

Derivation of the Bending Bearing Capacity Formula of Concrete-filled Steel Tubular Shear Wall

钢管混凝土束剪力墙是钢结构装配式建筑的一种形式,可在高层和超高层建筑中使用,有较大的发展前景.运用全截面塑性的基本概念,提出了4个基本假定,依据这4个基本假定推导出了端部未加强的一字型钢管混凝土束剪力墙的混凝土受压区高度和受弯承载力计算公式.

Concrete-filled steel tubular shear wall is a form of steel structure assembled building, which can be used in high-rise and super high-rise buildings, and it has a great development prospect. Applying the basic concept of full-section plasticity, four basic assumptions are proposed. Based on these four basic assumptions, the formulas for calculating the height and bending capacity of the concrete compression zone of the 1-shaped concrete-filled steel tube bundle shear wall with unreinforced ends are derived.
