Diagram 1 shows the interaction between the shear forces parallel and right-angled to the joint. For this, v Rd, must be multiplied with a design factor. If both shear forces occur an interaction is necessary, then the shear force right-angled to the joint (v Rd, ) can only be considered partly.

arranged as a ring beam or other constructive measures (e.g. This tensile force can be transferred via appropriate reinforcement e.g. Values for the design shear resistance parallel to the wall (V Rd,II ) as well as right-angled to the wall (v Rd, ) are as follows: If there are shear forces right-angled to the joint, a tensile force must be considered, which is one and a half times of the transferred shear force. The structural engineer is responsible to design the elements and to prove the joint connection according to the German approval (Z ). Furthermore, the precast units have to be made of normal weight concrete with a strength class of at least C30/37 according to EN 206. Tensile forces in the joint (along the wall) have to be excluded or taken by appropriate static or constructive measures Picture 5 Picture Picture 7 Picture PHILIPP GmbH, Aschaffenburg Technical changes and errors reserved AugustĦ Design and construction The reinforced precast concrete units to be connected must correspond to EC 2.

Primarily, it transfers static shear loads parallel and right-angled to the wall. 140 Range of applications and examples The Power Box System can be used for almost all connections of reinforced precast concrete wall elements. Picture 4 B500A Ø10 Stirrup Ø8/250 anchoring length acc. Higher joints are possible if the subsequent grouting of the joint is made step-by-step in sections of 3.5 m with a grouting hose. In general, a maximum joint height of 3.5 m is allowed. If shear forces right-angled to the joint have to be transferred the wall thickness must be increased to 18 cm.
