Diaphragms for seismic loading Part 2: A philosophy for analysis and design

As all structural engineers familiar with building design know, diaphragms constitute an integral part of the lateral-load resisting system. When the load under consideration is seismic, the diaphragms themselves often constitute a majority of the inertial mass, as well as the means of delivering inertial forces to the vertical elements of the seismic-load resisting system (SLRS). This article is the second in a two-part series.

2009 IBC Section 1613.6.7: Minimum distance for building separation

The 2009 International Building Code (IBC) Section 1613.6 includes eight alternatives to the 2005 American Society for Civil Engineers’ Minimum Design Loads for Buildings...

Structural changes in the 2012 International Building Code

Part II of this two-part article provides a brief overview of the more significant changes to Chapter 16 of the 2012 IBC, including wind...

ASCE 7-05: Seismic design of free-standing walls

Free-standing walls, typically of concrete or masonry construction, have numerous functions such as separating adjoining properties, screening service areas, and protecting pools. No permit or inspection is required for such walls 6 feet or less in height per the 2006 International Building Code (IBC) Section 105.2.

How to determine structural loads Part 2: Snow and rain loads in accordance...

Chapter 16, Structural Design, of the 2006 International Building Code (IBC) prescribes minimum structural loading requirements that are to be used in the design of all buildings and structures. The intent is to subject buildings and structures to loads that are likely to be encountered during their life span, thereby minimizing hazard to life and improving performance during and after a design event.

Changes to the Wind Load Chapter of ASCE 7

The reorganization of the wind loads section, addition of tabulated wind pressure data, and the new base for mapped wind speeds in the new edition of ASCE 7 should simplify calculations of some wind loads and create more uniform reliability in the design of structures.
