摘要:
推导普遍适用的部分预应力砼梁截面的弯矩-轴力-曲率的关系.基于砼、预应力筋的和非预应力筋的应力-应变关系的非线性和超静定结构的次弯矩,计算不同配筋的边跨梁和中跨梁.计算结果表明,配筋指标在0.1~0.25范围内,梁具有良好的延性和承载能力; 提高有效预应力和相应减小预应力筋面积,能提高梁的延性.
Abstract:
With respect to a partially prestressed concrete beam, the relation between bending monent-axialforce-curvature of its section is derived for general use. Based on the nonlinearity of stress-strain relation between concrete, prestressed reinforcement and
