ATC 40 : Seismic Evaluation and Retrofit of Concrete Buildings

AISC Design Guide 19 : Fire Resistance Of Structural Steel Framing

An important objective of building codes and regulations is to provide a fire-resistive built environment. Thus, building fire safety regulations contain numerous provisions including directives for the minimum number of exits, the maximum travel distances to exits, minimum exit widths, fire compartment requirements, fire detection and suppression mandates, and the protection of structural members in buildings. The focus of this design guide is the fire protection of structural steel framing systems. The guide is arranged such that important information for fire protection design, including that for building codes and test standards, is repeated within the design chapters to allow them to function as self-containing, stand-alone sections.

AISC Design Guide 18 : Steel-Framed Open-Deck Parking Structures

Steel-framed parking structures are increasing in popularity. The recent trend toward steel has prompted industry analyst Dale Denda of the Parking Market Research Company to comment that “exposed steel-frame construction is back as a recognized option for multi-story parking structures.” (Parking Today, June 2001)

AISC Design Guide 17 : High Strength Bolts

There are two principal types of fasteners used in contemporary fabricated steel structures—bolts and welds. Both are widely used, and sometimes both fastening types are used in the same connection. For many connections, it is common to use welds in the shop portion of the fabrication process and to use bolts in the field. Welding requires a significant amount of equipment, uses skilled operators, and its inspection is a relatively sophisticated procedure. On the other hand, bolts are a manufactured item, they are installed using simple equipment, and installation and inspection can be done by persons with only a relatively small amount of training.

AISC Design Guide 15 : Rehabilitation And Retrofit Guide

AISC and other specifications for the design of structural steel usually refer to standards published by the American Society for Testing and Materials (ASTM). Table 1.1a presents a historical summary of the pertinent ASTM standards for structural steels for buildings over the last century, with the relevant yield points and tensile strengths specified.

AISC Design Guide 14 : Staggered Truss Framing Systems

The staggered-truss framing system, originally developed at MIT in the 1960s, has been used as the major structural system for certain buildings for some time. This system is efficient for mid-rise apartments, hotels, motels, dormitories, hospitals, and other structures for which a low floor-to-floor height is desirable. The arrangement of story-high trusses in a vertically staggered pattern at alternate column lines can be used to provide large column-free areas for room layouts as illustrated in Fig. 1.1. The staggered-truss framing system is one of the only framing system that can be used to allow column-free areas on the order of 60 ft by 70 ft. Furthermore, this system is normally economical, simple to fabricate and erect, and as a result, often cheaper than other framing systems.

AISC Design Guide 12 : Modification Of Existing Welded Steel Moment Frame Connections For Seismic

The January 17, 1994 Northridge Earthquake caused brittle fractures in the beam-to-column connections of certain welded steel moment frame (WSMF) structures (Youssef et al. 1995). No members or buildings collapsed as a result of the connection failures and no lives were lost. Nevertheless, the occurrence of these connection fractures has resulted in changes to the design and construction of steel moment frames. Existing structures incorporating pre-Northridge1 practices may warrant re-evaluation in light of the fractures referenced above. The work described herein addresses possible design modifications to the WSMF connections utilized in pre- Northridge structures to enhance seismic performance.

AISC Design Guide 11 : Floor Vibrations Due To Human Activity

The primary objective of this Design Guide is to provide basic principles and simple analytical tools to evaluate steel framed floor systems and footbridges for vibration serviceability due to human activities. Both human comfort and the need to control movement for sensitive equipment are considered. The secondary objective is to provide guidance on developing remedial measures for problem floors.
