(1) AASHTO-LFRD In AASHTO-LFRD, the idea of crack control is proposed instead of cracking width calculation. The spacing of reinforcements is specified directly. In this case, it turns convenient for designers to confirm concrete serviceability and durability. Nevertheless, the crack control idea focusing on spacing of reinforcements. 想請(qǐng)教 這個(gè)dc 怎么理解? where ωmax is the maximum crack width; β is the ratio of the distances to the neutral axis from extreme tension fiber and the neutral axis from the edge; fs is the stress calculated in the reinforcements at service load; dc is the bottom cover measured from center of lowest bar.; and s is the maximum bar spacing. When using this equation to calculate crack width, test reinforcement stress value was substituted to the equation for fs. |
