Design of Longitudinal Reinforcement for Slabs
The design of reinforcement is performed for load caused by the bending moment M. The program provides the required area of tensile and compressive (if needed) reinforcement. It takes into account conditions for the minimum and maximum degree of reinforcement in a given cross-section. First, the program determines the depth of the compression zone as (Art. 6.2.10):
Providing the depth of compression zone is less than the allowable one (x < ξbh0), the program determines the area of tensile reinforcement Ast from the expression:
Providing the depth of compression zone is greater than the allowable one (x > ξbh0), the program determines the areas of both compressive Asc and tensile Ast reinforcement from the expressions:
The limit depth of compression zone ξbh0 is found from (Art. 6.2.7):
The computed degree of reinforcement is checked using the following expressions (Art. 8.5.1):
