61500 Providing a structural element Floor Plate will take care of the constraint. nevertheless, through the propagation process, someone can formulate some extra constraints. For instance, someone now requires some structural component(s) that can gather the weight from the floor plate and effectively transmit it to the ground. Thus, the constraints that may be devised may occur from structural deliberations or exogenous such as constructibility, mechanical and architectural considerations. Thus, constraints emanating from various domains might interact with one another, hence building mutual constraints. For instance, considering a high-rise office building floor system, in a characteristic floor system, architectural and mechanical components (ceiling and ductwork) are also present together with structural components such as floor slab and girder. Therefore, mechanical depth, ceiling height and structural depth form a mutually constrained combination such that when considered in together with the needed floor-to-ceiling height, they must not contravene the controls on the tolerable floor-to-floor height. The result of such an association is that disparity in the constraints of some domain may affect the choices in other domain(s).Hence if the mechanical ducts depth is enlarged, one may be forced to minimize the depth of girders or, otherwise, if the ducts were primarily beneath the girders, they might now have to be passed via the girders. The 2 top-level classes of constraints, specifically exogenous constraints and structural constraints can be further decomposed according to the classification put forward by Luth.Thus the subclasses are illustrated diagrammatically as indicated in fig 1.1 and are explained in the two subsections that follow.
