**E**_{c }#### Concrete Material

Concrete is designated as C35. Accordingly, the 28-day cylindrical compressive strength of concrete is 35 MPa and its tensile strength is 2.071 MPa.

Elasticity module is;

Design strength is obtained by taking the concrete material safety coefficient of 1.5.

#### Reinforcement Steel Material

Minimum characteristic yield strength of reinforcement steel has 420 MPa, a tensile strength between 1.15 and 1.35 times the characteristic yield strength and B420C steel with a strain corresponding to the tensile strength of 8%.

The design strength f

_{yd }is obtained by taking the reinforcement steel material safety coefficient 1.15 .
