Strut-and-tie method (STM) is a very useful tool to design the irregular concrete members. This work presents the results of the experimental tests conducted on three self-compacting reinforced concrete deep beams that had a constant cross section of 150 mm×400 mm and a total length of 1400 mm.In this study, a strut-and-tie model (STM) for predicting the shear strength of reinforced concrete deep beams and corbels was proposed. The model was derived on the basis of two independent force ...Deep pier caps possess additional shear strength due to the formation of the strut action which cannot be captured by the traditional sectional method. The strut-and-tie method (STM) is a suitable ...Guan 2005 analyzed eleven deep beams with web openings through the topology optimization of the models Strut-and-Tie Method (STM). Wu and Li 2009 analyzed two continuous beams with square and ...The shear capacity predictions of deep beams obtained from the present models are in better agreement with 637 test results than those determined from strut-and-tie models proposed by ACI 318-08 ...

A strut-and-tie model for a beam is shown in Figure 1.1. Due to the close spacing of the loads and support reactions, the entire member is classified as a D-region. After developing a strut-and-tie model, a designer must ensure the structure has the required capacity to carry the tensile and compressive forces indicated by the model. The strut ...Sep 8, 2022 · 3.1 Deep Beams. Reinforced concrete deep beams are one of the typical D-regions, which are usually included in a design code to show the design procedures and fundamental provisions of the strut-and-tie method. For a simple deep beam subjected to a uniform load on the top, the distributed load can be simplified as two equivalent point loads. This case is from Prof. James K. Wight's paper " Strut-and-tie model for deep beam design ". First of all, I repeated the STM model of Prof. Wight, but converted all the English units into metric units. It is a practice for me. Secondly, I choose a different STM model and try to figure about whether this simpler triangle STM model could work. ….
