![]() ![]() ![]() If a structure is designed solely to minimize material cost, the design is likely to include many different member sizes but this practice is actually somewhat inefficient, because there are added costs associated with ordering all of these different sizes, managing them on the jobsite, and connecting different-sized members together. ![]() The product cost represents an important real-world aspect of structural engineering design–that standardization of member sizes can improve overall cost-efficiency. In this circumstance, if the cost saving due to the reduced member size is less than $1,000, the overall cost of the bridge will increase. When you reduce the size of a member, you reduce its material cost however, if the modified member is a unique new product (i.e., if its material, cross-section shape, and size are different from any other member in the structural model), then the product cost is increased by $1,000. The cost of a given bridge design consists of three components–material cost, connection cost, and product cost. To understand how reducing the size of a member can sometimes cause the overall cost of the bridge to increase (and how increasing a member size can sometimes cause an overall decrease in cost), you must first understand how the Bridge Designer calculates the cost of your bridge. ![]()
