“…It includes strut geometry (which governs the size of the loading and support plates and strut length) and strut boundary conditions (which governs the spacing and diameter of web reinforcement that run transverse to the struts). The modified model yields better agreement than the original STM [22] in terms of accuracy and consistency. Through the modified model and the test program, the authors hope this work may shed some light on this interesting phenomenon of size effect on deep beams.…”

“…The authors proposed a modified Strut-and-Tie Model (STM) incorporating causes of size effect based on a previous proposed model (Tan and Cheng [15], Zhang and Tan [22]). It includes strut geometry (which governs the size of the loading and support plates and strut length) and strut boundary conditions (which governs the spacing and diameter of web reinforcement that run transverse to the struts).…”

“…Extended from Mohr-Coulomb failure criterion, Tan et al [20] proposed an equation for the ultimate shear strength V n . Later, Zhang and Tan [22] improved the STM for greater prediction consistency and accuracy (referred to as "original STM"), and proposed the expression for V n as follows:…”

“…MacGregor (10) showed that the ductile behavior of continuous deep beams can be ensured by the use of strut-and-tie models. Recently, direct strut-and-tie model accounting for stress-distribution factors was proposed and verified by experiment (11) , and a new model which takes into account the effect of the support stiffness in continuous deep girders was suggested (12) . However, the adopted example was a two-span deep girder that transmits the load from the upper columns to the off-set lower columns.…”

Two design approaches, conventional and strut-and-tie procedures, are developed for reinforced concrete continuous deep girders which transmit the gravity load from the upper wall to the lower columns. This paper presents the results of tests and analyses conducted on two specimens; the first specimen employs the conventional procedure, while the strut-and-tie procedure is used for the second specimen.The conclusions are as follows: (1) The approach of the strut-and-tie method is valid for this type of continuous deep girder rather than the conventional beam approach. (2) Since the upper load is carried over directly to the supporting column through the stiff concrete strut to the point of yielding of the bottom ties, the shear capacity of continuous deep girders is mainly governed by the yielding forces of the bottom ties. (3) The additional shear resistance derives from continuity with the adjacent beams or walls. Shear and top reinforcements in the continuity region can be designed by using appropriate models for the additional margin of safety in terms of strength and ductility. (4) Simulation through two-dimensional nonlinear analyses using DIANA shows a good correlation with the experimental results.
