【摘要】 部分预应力B类构件选择钢筋的名义拉应力法与裂缝验算公式之间的协调性是本文探讨的主要问题。通过大量的对比计算分析,探讨两者的协调性,并提出对名义拉应力法确定预应力钢筋数量计算公式的修正意见,得出适用于部分预应力B类受弯构件配筋方法。更多还原

【Abstract】 The compatibility between the nominal tensile stress’s calculuses for partially prestressed member B to select reinforcements and the crack checking formula is a main problem which the paper will make approach to.Through vast amount of contrast calculations,the paper has examined both’s copatibility,and submited amendments to computing formula for determining quantity of pressed reinforcements by nominal tensile stress’s calculuses,finding the reinforcing methods suitable for flexural member B,partially prestressed.更多还原
