Determination of Wind Loads

Wind loading as described in Art. 9.1 is the basis for design wind loads specified in Minimum Design Loads for Buildings […]

Description of Wind Forces

The magnitude and distribution of wind velocity are the key elements in determining wind design forces. Mountainous or highly developed urban

Cable Structures

High-strength steel cables are very efficient for long-span roof construction. They resist loads solely by axial tension. While the cables are

Dome Roofs

These are preferable to arches where the large column-free area to be covered is circular, elliptical, or approximately an equal-sided polygon.

Arched Roofs

These are advantageous for long bays, especially if large clearances are desirable along the center. Such braced barrel vaults have been

Space Frames

These represent one of the more efficient uses of structural materials. Space frames are threedimensional lattice-type structures that span in

Plate Girders

For long spans or heavy loadings that exceed the capacity of standard rolled shapes, plate girders can be used. Plate


Although a floor system may be adequately designed from a strength standpoint, a serviceability problem will result if unacceptable vibrations

Fire Protection

There are several methods by which fire ratings can be readily achieved for structural-steel floor framing systems. These methods include application

Dead-Load Deflection

Although, in general, building codes restrict the magnitude of live-load deflections, they do not contain criteria or limitations relating to dead-load
