in this paper a new method based on strut-and-tie model (stm) is proposed to determine the shear capacity of simply supported rc deep beams and an efficiency factor for concrete with considering the effect of web reinforcements. it is assumed that, the total carried shear force by rc deep beam provided by two independent resistance, namely diagonal concrete strut due to strut-and-tie mechanism ...

This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced concrete beam-column connections. Developing strut-and-tie models in reinforced concrete beam-column connections is treated as a topology optimizatio...

Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calcula...

The main objective of this study is to propose the Strut-and-Tie method (STM) to predict the shear capacity of simply supported RC deep beams shear-strengthened with carbon fiber reinforced polymers (CFRP). It is assumed that, the total carried shear force by shear-strengthened RC deep beam provided by three independent resistance, namely diagonal concrete strut due to Strut-and-tie mechanism, ...

To reduce the thickness of reinforced concrete foundation members used in construction and structural applications, a previous study developed tested strut–tie retrofit system installed foundations. This proposes optimum details steel-tie for with reduced via finite element simulation-based load-bearing capacity assessment. The parameters (structural steel type, plate thickness, number strut fr...

Strut-and-Tie Models (STM) for the design of concrete beams, comprising of struts, ties, nodes as the basic tools, is conceptually simple, but its realization for complex concrete structure is not straightforward and depends on flow of internal forces in the structure. STM technique has won wide acceptance for deep member and shear design. STM technique is a unified approach that considers all ...
