MICROCONCRETE MODEL CONSTRUCTION OF A PRESTRESSED SUSPENDED ROOF.
Abstract
Construction of the microconcrete model revealed that small diameter aircraft cable and microconcrete are excellent model materials. Extensive preliminary material testing must precede the actual construction if satisfactory results are to be achieved. Much forethought must also be given to the design of the model frame so buckling will not occur when heavy loads are applied. Movement of the frame must particularly be avoided in models of suspended roofs because small horizontal movement of the frame results in large vertical deflection of the roof cables. A circular plan form is, therefore, more desirable than a rectangular plan. Weighting of a suspended roof requires a great quantity of material and unless space is reserved under the formwork, the construction of the model is considerably complicated. (Author)
