WebAug 3, 2004 · I have casually reviewed the IBC 2000 Section 1913. Basically what they are checking for is the resultant shear capacity of the cone(s) that are developed beginning from the head of the AB to the nearest surface and/or other adjacent cones. This is assuming that the concrete shear will take all of the load. WebThe maximum shear stress associated the minimum strut angle of θ =21.8º (when cot θ = 2.5) is relatively high (e.g. 3.64 MPa for a C30/37 concrete).

WebApr 1, 1988 · Formwork for conical and egg-shaped tanks and water towers is made of radial steel I-beam supports with small trapezoidal panels about 20 inches high wedged tightly between them. Steel formwork for cylindrical structures up to 130 feet in diameter is fabricated with rigid tubular steel rings that hold inner and outer sheathing. WebReo (eye) Anchors. These anchors are used with a hanger bar, also known as a tension bar, where the concrete is too weak for a cone anchor. They are ideal for thin panels and other applications where the concrete shear cone developed by the anchor is insufficient to provide the working load limit of the anchor e.g. low strength concrete.
