CAM Software – Understanding and Using CAM

The decision to use CAM or not is largely dependent upon both the time and geometry of the item to be manufactured. Often, users either already have a CAD drawing or can rather quickly produce one to obtain any required dimensions in which to reproduce the item. The use of CAM affords the user to … Read more

CAD and Graphics

I would assume that almost all the readers of this text have already heard of the acronym CAD (computer-aided drafting). However, I will not assume that everyone has worked with it. CAD is the graphical process of drafting a part or an intended area, with vectors, in which CAM operators will be applied. It is … Read more

Wood floor framing construction

  Sills on Foundation Walls Sills resting on continuous masonry foundation walls are generally of nominal 2×4 or 2×6 lumber. They are an- chored to masonry walls with ½-inch bolts at approximately 6-foot intervals. Bolts are embedded at least 6 inches in poured concrete walls and at least 15 inches in masonry block walls, Figure … Read more

Permanent Wood Foundation

Floors and roofs are covered with 2-inch planks. These serve as subflooring and roof sheathing, and, where tongue-and-grooved planking is used, provide an attractive finished floor and ceiling. Ends of floor and roof beams are supported on posts which provide the wall framing. Supplementary framing between posts permits attachment of wall sheathing andexterior sidings. Details … Read more

Suggestions for Design

Economy of concrete structures begins in the design development stage with designers who have a good understanding of formwork logic. Often, two or more structural alternatives will meet the design objective equally well. However, one alternative may be significantly less expensive to build. Constructability, that is, making structural frames faster, simpler, and less costly to … Read more

Plate Structures

Plate structures are rigid, planar, usually monolithic structures that disperse applied loads in a multidirectional pattern, with the loads generally following the shortest and stiffest routes to the supports. A common example of a plate structure is a reinforced concrete slab. A plate can be envisioned as a series of adjacent beam strips interconnected continuously … Read more

Building Systems

Structural System The structural system of a building is designed and constructed to support and transmit applied gravity and lateral loads safely to the ground without exceeding the allowable stresses in its members. The superstructure is the vertical extension of a building above the foundation, Columns, beams, and loadbearing walls support floor and roof structures. … Read more
