一、引言钢筋混凝土深梁是工程中常见的构件,不论在水工建筑、工业民用建筑、海港码头、矿山工程等许多方面部有应用。例如,水电站厂房的尾水深梁,承受起重机的深梁,高桩码头的横梁,大型预制简支墙板,煤仓深梁等。由于深梁并不符合平面变形基本假定,因此,建立在材料力学基础上的普通钢筋混凝土结构的极限荷载设计方法和规定并不完全适合深梁。传统的线弹性应力设计方法往往又与实际出入较大。正因为这样,外国对深梁进行丁大量的试验和理论研究工作,并且相继制订了深梁的有关规范。
I. INTRODUCTION Reinforced concrete deep beams are a common component of the project and are applied in many aspects such as hydraulic construction, industrial civil construction, harbor docks, and mine engineering. For example, the tail water deep beams of the hydropower plant, the deep beam of the crane, the beam of the high-pile wharf, the large prefabricated simple-supported wall plate, the deep beam of the coal bunker, etc. Because the deep beams do not meet the basic assumptions of plane deformation, the ultimate load design methods and regulations for ordinary reinforced concrete structures based on material mechanics are not entirely suitable for deep beams. The traditional linear elastic stress design method is often quite different from the actual one. It is precisely because of this that foreign countries conducted extensive experiments and theoretical studies on Shen Liang, and successively formulated the relevant norms of Shen Liang.
