委员会说明本建議意图对設計工程师提供一項应用于預应力損失計算的研究数据的綜合性总結。它提供了作为时間函数的預应力損失計算的一般方法。本报告包括应用于建筑方面的預应力損失計算的资料和程序,一般方法也可应用于桥梁,虽然它和美国公路协会的公路桥梁的标准規范在个別損失項目有某些不同。預应力混凝土杆件的应力損失的精确計算是一个复杂的問題,因为由于一个因素,如力筋松
Committee Note This Recommendation intends to provide design engineers with a comprehensive summary of the research data applied to the calculation of prestress loss. It provides a general method for calculating the loss of prestress as a function of time. This report includes information and procedures applied to the calculation of prestress loss in construction. The general method can also be applied to bridges, although it differs somewhat from the standards set forth by the NHA for road bridges in individual loss items. Accurate calculation of the stress loss of prestressed concrete members is a complex problem because, due to one factor,
