This seminar discusses the major new features of the 2015 IBC structural provisions. Subjects covered include substantive revisions to structural-related Chapters 16-23, Supplement No. 1 to ASCE 7-10 (which is now adopted by the 2015 IBC), and referenced standards which have been updated in 2015 IBC Chapter 35. There will also be an opportunity for participants to ask questions. This seminar is designed to provide a great introduction to the 2015 IBC and assist the code user in making the transition to the new code.

Duration: 4 hours

A significant part of this seminar will be devoted to the complete reorganization of ACI 318, which has taken place from its 2011 to its 2014 edition, where it is now a member-based document. Toolbox chapters, new chapters, and reshuffled chapters will be explained and clarity will be provided so that engineers will be “ready to go” when they need to begin working with the new standard in concert with the 2015 IBC.

The adoption of ACI 318-14 by the 2015 IBC and the modifications made by the 2015 IBC to the provisions of ACI 318-14 will also be discussed.

Duration: 4 hours

The seminar presents the requirements for seismic design using structural dynamics, with emphasis on the modal response spectrum analysis method. Theoretical background information on modal response spectrum analysis as well as a clear, step-by-step procedure for designs based on such analysis is presented. Engineers, code enforcement officials, building designers, faculty, and advanced students seeking an understanding of seismic design based on dynamic analysis would benefit immensely from this seminar. The seminar is based on ASCE 7-10 and the 2012 IBC.

Duration: 4 hours

This seminar discusses major features that are new to the 2012 IBC structural provisions which reference ASCE 7-10, Minimum Design Loads for Buildings and Other Structures. Changes to the structural loading requirements as well as to the special inspection, foundation, and material provisions are presented. Subjects covered include updated material standards, revised load combinations, new live loads, new ponding requirements, revisions to wind and seismic design provisions, and new provisions in Chapters 17 and 18. This seminar material is designed to provide a great introduction to the 2012 IBC and assist the code user in making the transition to that code.

Duration: 8 hours

The structural provisions of the 2012 IBC are very different from those of the 2006 IBC – primarily because the referenced standard for design loads has changed from ASCE 7-05 to ASCE 7-10. The updated edition contains substantive changes in seismic design provisions, wind design provisions, snow load provisions, design load combinations, and a number of other areas. An overview of these changes will be provided. Importantly, except for the seismic design provisions, the 2012 IBC is not the same as ASCE 7-10. For instance, the new performance-based design provisions in Chapter 1 of ASCE 7-10 are not adopted by the 2012 IBC. The Alternate All-Heights Method of wind design, which was first introduced in the 2009 IBC and is not part of ASCE 7-10, has been kept in the 2012 IBC. The differences between the structural provisions of ASCE 7-10 and those of the 2012 IBC will be pointed out. The materials standards referenced by the IBC also changed from the 2006 to the 2012 edition. Because of time limitations, these changes will be mentioned but not discussed in detail.

Duration: 8 hours

This seminar presents a detailed and comprehensive overview of the substantive changes from ASCE 7-05 to ASCE 7-10. Major revisions took place in both the wind design and the seismic design provisions. Wind design changed more drastically than at any time since the publication of ASCE 7-95. The reorganization of the wind provisions is discussed and the changes to the wind maps and the corresponding changes to the load factors are explained. In addition, the new simplified version of the general analytical procedure under Method 2, which is applicable to buildings of all heights, is addressed.

Four major changes to the seismic maps are presented and reasons as to why these changes were found necessary and how they will affect seismic design results are explained. There are many other significant changes to the ASCE 7 seismic provisions, such as changes to Table 12.2-1 (the R-values table), that are discussed.

In addition to covering changes to the wind and seismic provisions, the seminar also presents a detailed and fairly comprehensive overview of the substantive changes to the provisions for the other types of loads found in ASCE 7. These include the introduction of performance-based design procedures, replacement of occupancy categories with risk categories, enhancement of the general structural integrity requirements, and so forth.

Duration: 8 hours

Ever since Appendix D, Anchoring to Concrete, was introduced in the 2002 edition of ACI 318, the design of anchors subject to seismic forces in structures assigned to Seismic Design Category (SDC) C and above has been problematic. Real relief has finally been provided in ACI 318-11. This seminar will discuss the significant revisions to the seismic design provisions for anchorage to concrete, including:

• A new 20% rule for invoking seismic design requirements

• Ductile anchor check for single anchors and groups

• A new 8da stretch length requirement

• Design options for anchors subject to shear.

The other big change in Appendix D of ACI 318-11 is the introduction of design provisions for adhesive anchors. These provisions will be briefly discussed.

Duration: 4 hours

The following topics are covered in this seminar:

1. A look at Chapter 19 of the 2012 IBC

2. Changes from ACI 318-08 to ACI 318-11 (excluding Appendix D changes)

3. 2012 IBC modifications to ACI 318 provisions (excluding Appendix D modifications)

4. ACI 318-08 Appendix D with a complete numerical example

5. Changes in Appendix D from ACI 318-08 to ACI 318-11 (including 2012 modifications to Appendix D).

Post-installed anchors used to be outside the scope of anchor design provisions in legacy model codes. Provisions for post-installed mechanical anchors are discussed. There are two major changes in Appendix D from ACI 318-08 to ACI 318-11 – changes in seismic design provisions and introduction of new provisions on adhesive anchors. The seismic changes are particularly important because they do solve long-standing problems with seismic anchor design using this appendix. So, much of the seminar is devoted to these changes. The 318-08 Appendix D provisions are gone over first, using a numerical example to effectively get the provisions across; the changes made in ACI 318-11 are then discussed. This puts the changes in context and makes them easier to understand and to appreciate. In the second segment above, all the non-Appendix D technical changes from ACI 318-08 to ACI 318-11 are discussed. Some of the changes in Chapter 21, Earthquake – Resistant Structures, are important and have far-reaching consequences.

Duration: 8 hours

ACI 318-11 Appendix D contains provisions for cast-in-place, post-installed mechanical, as well as adhesive anchors.

The seminar illustrates the four different failure modes for a group of anchors subject to tension and three different failure modes for a group of anchors subject to shear, and the calculation of the corresponding anchor strengths through a complete design example. The related detailed provisions of Appendix D are introduced and discussed in the course of presenting the example. The strength of an anchor or a group of anchors subject simultaneously to tension and shear is also discussed, as well as the prevention of splitting failure. Important changes from ACI 318-08 to ACI 318-11 are explained.

Post-installed anchors used to be outside the scope of anchor design provisions in legacy model codes. Provisions for post-installed mechanical as well as adhesive anchors are discussed.

Duration: 8 hours
