註釋

An analytical investigation was conducted to study the development and suitability of the more recent inclined cracking theories. It involved a comprehensive examination of the development of diagonal or inclined cracks and the factors affecting such cracking in reinforced concrete beams without web reinforcement. Six different inclined cracking theories and their basic assumptions are presented, showing how the critical shear and diagonal tension stresses are computed according to each of the theories. The relative merits of each expression are then compared with observed behavior. The empirical correlation of calculated values with the corresponding observed inclined cracking loads for 194 test beams indicated that the AC1-ASCE Committee 326 Equation gave the best general solution.
