  • Concrete Reinforcing Mesh Calculator - Inch Calculator

    Concrete Reinforcing Mesh Calculator - Inch Calculator

    Step One: Calculate the Slab Area. The first step to estimate reinforcement is to find the size of the concrete slab that will be poured. If you already know this figure, then you can skip ahead to the second step. The area of the pour can be found by multiplying the length in feet by the width in feet. The result is the square footage of the slab.

    Prestressed Concrete Bridge - an overview | ScienceDirect

    The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

  • What is Slenderness Ratio of RC Column and How to

    What is Slenderness Ratio of RC Column and How to

    The slenderness ratio of a reinforced concrete (RC) column is the ratio between the length of the column, its lateral dimensions, and end fixity. It assesses the ability of the reinforced concrete column to resist buckling pressure. The slenderness ratio is calculated by dividing the column length by its radius of gyration. The slenderness ratio […]

    Nov 06, 2008 What is the maximum speed with which a 1900 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.) The answer is 34 m/s, and I would like to know why. I can't get a good image in my head of what this curve looks like. I've googled the question and found several people having asked it before with different values, but ...
