Issues in Post-tensioned Construction| Concrete ...Jan 06, 2006· A good rule of thumb is that a post-tensioned system will move about 1 inch for every 100 feet of slab that is not restrained by a lateral system. If the edge of the slab is 50 feet away from the nearest shear wall, when post tensioned this edge will move in about ½ inch.CHAPTER 5 - FOUNDATION REQUIREMENTSthe projection on each side of the wall, pier, or column exceeds 2/3 of the footing thickness, or when required because of soil conditions. 503-4.

Thumb rule for estimating the Concrete Volume with respect to the area:. The volume of concrete required = 0.038 m3/square feet area. Example:-If Plan Area = 40 x 20 = 800 Sq. m. So, for the plan area of 800 Sq. m. the area the total volume of concrete requiredControl Joints, Expansion Joints and Cold Joints in ...A basic rule to follow when judging how deep a control joint should be is that it should be roughly 1/4 the depth of the concrete.
