Equations for Shear Design of Continuous Reinforced-Concrete Haunched Beams Based on Stress Fields and Truss Models
Publication: Practice Periodical on Structural Design and Construction
Volume 25, Issue 3
Abstract
Simple methods are required to reasonably estimate the shear strength of reinforced-concrete haunched beams (RCHBs) for design in order to inhibit shear failures in favor of a flexural behavior. In this paper, design equations developed from stress fields and truss models, also known as strut-and-tie models, are assessed and related with the processed experimental data for the cyclic testing of continuous RCHBs failing in shear. It was found that, for design purposes, plausible estimates for the shear strength of RCHBs could be assessed with the proposed equations.

Acknowledgments
The financial support of Conacyt (Basic Science Project 79878) and Universidad Autónoma Metropolitana is gratefully acknowledged. The HESA firm fabricated all the steel (including the continuous inclined steel reinforcement) used in all the tested specimens. Edznab López heavily participated in the design of the formwork and the construction and testing of most specimens. Jesús Aranda participated in the testing of beam TASCV3α4-R1c as a part of his BSc. thesis. MSc. Gilberto Rangel, Eng. José Rivera, and technicians Rubén Barreda, Juan Mateos, and José Caballero assisted us in the prototype testing.
