reinforcement strength characteristics

Heavy concrete, class B30: prism strength Rb = 17MPa,

Axial tensile strength Rbt = 1.2 MPa.

Concrete working condition factor αb2 = 0.9.

Fittings longitudinal class A300 with a rated resistance to Rs=280 MPa stretching.

Transverse reinforcement - wire of class Bp1, diameter 5 mm in welded roll mesh, Rs = 260 MPa.

Calculation of cross-bar strength in sections normal to longitudinal axis

5.6.1. Strength characteristics of concrete and reinforcement.

Heavy concrete, class B25; design compression resistance Rb = 14.5MPa under tension Rbt = 1.05 MPa; concrete operating condition factor αb2 = 0.9; elastic modulus Eb = 30000 MPa.

Reinforcement longitudinal working class AII with Rs = 280 MPa, modulus of elasticity Es = 210000 MPa.

Designing Girdle Wireframes

The girder is reinforced by two vertical welded frames. In order to reduce metal consumption, part of the longitudinal reinforcement of the girder is cut off in the span. You must create a material symbol to define the breakaway locations. The broken rods are brought behind the places of theoretical break by the length of the anchor W.
