Larry Griffis: Seismic vs. Wind – Which Controls?
Oftentimes in low and moderate seismic zones, the design engineer is faced with the question early in preliminary design about whether wind or seismic loads will govern the design. This presentation will focus on this question and offer some guidance on a rational preliminary design procedure to use for a project. Particular attention will be given to important aspects of
establishing the structural system as it relates to the design for both seismic and wind loads.
Sharon Wood: Seismic Design Provisions in ACI 318-08
This presentation will provide a brief overview of the seismic design provisions for reinforced concrete buildings in the 2008 edition of the ACI Building Code. Many of the changes in ACI 318-08 were intended to integrate the detailing provisions for reinforced concrete construction with the procedures used to define the design loads in the International Building Code.

Tour of Ferguson Structural Engineering Laboratory and the NEES Equipment Site at the University of Texas
The Ferguson Structural Engineering Laboratory is located on the Pickle Research Campus of the University of Texas at Austin (http://www.utexas.edu/research/fsel/): Ongoing research at the laboratory is related to the behavior of concrete, steel, and masonry structures, durability of concrete bridges, fatigue of steel structures, fire performance of steel buildings, and nondestructive testing of concrete structures.
The NEES equipment site (nees.utexas.edu) includes three, large-scale, geotechnical shakers, which enable dynamic field testing of soil, foundations, and structures. Tests to date have included studying the sediments in the Mississippi embayment, development of a community velocity model for the Salt Lake Valley Basin, and seismic risk mitigation of port facilities.
Richard Klingner: Update on the 2008 MSJC Code and Specification
In this presentation, the changes from the 2005 to the 2008 MSJC Code and Specification are reviewed. Of particular interest will be the seismic provisions, which have been made more transparent and more closely linked to expected performance.
Richard Klingner: Autoclaved Aerated Concrete Masonry: Technical Background, Code Implementation and Design Examples
Autoclaved Aerated Concrete (AAC) is a lightweight, environmentally friendly material that has just been accepted into the 2007 IBC Supplement for zones of low and moderate seismicity. In this presentation, the technical background behind the structural use of this material is explained; MSJC design and construction provisions for AAC masonry are reviewed; and design examples are provided.
John Henry: Seismic Design of Wood Structures
The 2005 Special Design Provisions for Wind and Seismic (SDPWS) and 2005 National Design Specification® for Wood Construction (NDS®), referenced in 2006 IBC and ASCE 7-05, provides design requirements for wood-frame shear walls, diaphragms, members and connections. An overview of key provisions,
recent changes, and application to seismic design of wood-frame
buildings is provided.
Mike Engelhardt: Seismic-Resistant Design of Steel Structures and the 2005 AISC Seismic Provisions
This presentation will provide a brief introduction to the 2005 AISC Seismic Provisions for Structural Steel Buildings, with a discussion of key detailing requirements and an overview of the various seismic load resisting systems in steel. Strategies for seismic-resistant design of steel structures in areas of low and moderate seismicity will be discussed.
