“…Additionally, recently published experimental results show that some of the currently used models in practice cannot sufficiently accurate predict the shear capacity in some specific scenarios [12]. Here, both the CSM and some of the standards (e.g.…”

“…The main purpose of horizontal and vertical joints between panels or slabs is the perception of shear forces [14]. Experimental studies are limited to determining the optimal placement of reinforcement in the joints between wall panels, bridge plate joints [15][16][17], as well as issues of concrete work in the joint, issues of adhesion of panel concrete and butt concrete [18]. In addition, the issues of shear strength are also considered in relation to the construction of multi-layer wall panels [19][20][21], data on the flexibility of the reinforcement in the joints, the influence of its position on the nature of the destruction of the joints and the connected panels, the destructive loads are obtained.…”

Despite the widespread use of monolithic construction, precast concrete remains in demand in the construction of residential and administrative buildings. Regardless of the advantages in technology and the quality of work, it is necessary and appropriate to modernize the existing design solutions, which allows you to simplify and speed up the technological operations during construction. Moreover, in the construction of complex nodes and joints, the qualification of workers is important, so simplifying the work without losing the quality of construction and ensuring strength, stability and durability is an important task. This problem can be solved by using modern embedded parts in the joints that do not require welding and other complex technological operations. In this paper, a constructive solution of the horizontal joint of the floor slabs located in the zone of action of minimal forces is proposed on the example of a girderless frame. The purpose of the study is to determine the stress-strain state of the proposed structural solution of the horizontal joint of floor slabs using loopshaped embedded parts «PFEIFER» and to develop recommendations for determining the shear compliance. Based on the analysis of the results of numerical modeling, the features of the stress-strain state of the joint during shear operation are revealed. The results obtained can be used in the design of buildings with precast-monolithic ringless frames, in the modernization of existing standard solutions of precast-monolithic frames, as well as other load-bearing systems made of precast concrete.

Recently it has been shown that the effectiveness factors used in the crack sliding theory are not well suited for predicting the shear strength of beams with large depths. Therefore, formulas for the effective concrete compression strength and the effective tensile strength have been reformulated by changing the size effect factor and adding a term to take into account the maximum aggregate size. Also, the theory has been improved to predict better the shear strength of deep beams and beams with short shear span. This is done by including the effect of the transverse stress. Experimental data for slender beams and deep/short beams with rectangular cross sections have been used for validation of the crack sliding theory. The outcome of this analysis is that the new theory in general are substantially better for predicting shear strength than the old one.
