Selection of construction elements and processes

The design process frequently involves one or more areas not generally included in typical CADD software. These include: structural component analysis and selection and preferred techniques for construction. Application-specific software is available to aid the designer in making decisions that will improve the use, function, efficiency, or safety of a design.

Structural Analysis allows the designer to design building components able to withstand the building’s own stress and weight plus the impact of outside forces. Most nontraditional building designs require structural analysis to ensure design integrity. An architect uses descriptive analysis to calculate stress forces in unique residential structures and structural elements. Other common computer applications of structural analysis focus on the following:

- strength and elastic stability of building materials

- heat transfer

- pipe rupture and fluid-flow analysis

- conditions that exert force and strength.

Structural Component Selection. Great assurance is required that the structural components have enough strength to support the intended loads. Many of these structural components are available in new engineered-wood products, which are unfamiliar to many designers and builders. As a result, both do-it-yourselfers and professionals are turning to application-specific software programs to help them select components of the proper size and type for a particular application.

Some common computer programs related to analyzing and selecting structural components focus on the following areas:

- fixed arches and other supports

- steel-structure design

- structural members of frames, including cables, beams, and columns.

Computer Simulation. One of the more useful functions of the computer is its ability to simulate, or illustrate, results before the structure or system is built. For example, by changing the layout and/or mixing cabinets of different dimensions, the kitchen can be tailored to satisfy the client’s needs. A wide variety of computer simulation applications are available to show the ultimate results of changing various materials, designs, and systems affecting the home’s interior and exterior.
