Workshop Summary : Earthquake-Resistant Design of Buildings and Other Structures by 2018 IBC, ASCE 7-16, and ACI 318-14

The vertical components of earthquake ground motion are implicitly required to be considered in the seismic design of structures and structural members by U.S. codes and standards. A requirement was first introduced in the 1997 edition of the Uniform Building Code (UBC) and has been continued in all editions of the International Building Code (IBC) and in all recent editions of ASCE Standard 7 Minimum Design Loads for Buildings and Other Structures. In designs by ASCE 7/IBC, the dead load factor of 1.2 is increased by 0.2SDSD in the additive seismic load combinations where gravity effects add to earthquake effects. The dead load factor of 0.9 is decreased by the same 0.2SDSD in counteractive seismic load combinations where gravity effects counteract earthquake effects. 

ASCE 7-16, for the first time, has introduced a vertical ground motion spectrum but explicitly requires its use in the seismic design only of “tanks, vessels, hanging structures and nonbuilding structures incorporating horizontal cantilevers.”

This presentation will report on an investigation directed at exploring whether explicit consideration of vertical earthquake ground motion should be required for certain structures. To arrive at a determination, the treatment of vertical earthquake ground motion in the seismic design of structures in U.S. Codes, standards, and resource documents and in Eurocode 8 is reviewed. Highlights from a survey of information available in the literature on the features of vertical earthquake ground motion and its potential impact on structural design will be presented. Structures and structural members that appear to be more sensitive to the consideration or non-consideration of vertical earthquake ground motion in their designs are identified. In the absence of detailed studies to investigate the adequacy of the code-specified design force of 0.2SDSD for structural members subjected to vertical ground motion, an interim measure that might be considered in the seismic design of structures identified to be sensitive is proposed. 

The International Building Code (IBC) now serves as the basis of legal codes of cities, counties, and states across the United States.  The seismic design provisions of the IBC, based on those of ASCE 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, represent revolutionary changes from those of the model codes it replaced, including the Uniform Building Code (UBC), the seismic design provisions of which had world-wide influence.

The ground motion maps and parameters used in seismic design are different from those used in the past.  Also, since the inception of seismic design, soil at the site of the structure has not been given as much importance in seismic design as it is given in the IBC.  This results in a significant impact on the cost of construction, particularly if such construction is to be founded on softer soils.  The purpose of this seminar is to present a brief overview of the seismic design provisions of the IBC/ASCE 7 in a manner that is understandable to a broad audience. 

Seismic design, in its essence, is an exercise in tradeoff between strength and inelastic deformation capacity.  The higher the strength we are prepared to provide to a structure, the lower the need for inelastic deformation capacity; and the converse is also true.  Inelastic deformation capacity is the ability of a structure to continue to carry full factored gravity loads as if undergoes lateral displacements beyond the stage of elastic response (which, by definition, does not cause any residual displacement or damage).  Inelastic deformation capacity comes from proper detailing of the structural members and joints.  The detailing requirements are given in the materials chapters of the IBC, which refer to material standards.  In the case of concrete design and construction, the standard is ACI 318 Building Code Requirements for Structural Concrete.  The seismic detailing requirements of the 2014 edition of ACI 318, which are adopted by the 2018 IBC, are also discussed and explained as part of this workshop.

S. K. Ghosh's Publications on Sale

S. K. Ghosh has written and has contributed to many structural engineering related publications. Here you have the rare opportunity to buy some of his publications with discounted prices. The offered publications are :

  1. Seismic Design Using Structural Dynamics - price Rp 500.000,-
    The 2015 edition of the International Building Code (IBC) require the use of a dynamic analysis procedure for the seismic design of a building under certain conditions of irregularity, occupancy, and height. However, dynamic analysis procedures are more complicated than the more traditional static procedure, and over the years, many questions have been asked about code provisions concerning this. This publication has been created to answer these questions and demystify the application of the code.
    This publication addresses the two methods by which a designer may comply with the seismic design requirements of ASCE 7-10, which is adopted by the 2015 IBC: Equivalent Lateral Force Procedure (ASCE 7-10 Section 12.8) and Dynamic Analysis Procedure (ASCE 7-10 Section 12.9 and Chapter 16). Although ASCE 7-10 formally recognizes two dynamic analysis procedures: modal response spectrum analysis and time-history analysis, the modal response spectrum analysis is by far the more common in design office usage and is the primary subject of this publication. The background and details are explained in Chapter 1 of this publication where a step-by-step analysis procedure is given, and a three-story, one-bay frame example is solved entirely manually to illustrate application of the procedure.
    Chapter 2 of this publication is devoted exclusively to the detailed design of a 20-story reinforced concrete building that utilizes a dual system consisting of special shear walls and special moment frames for earthquake resistance. Modal response spectrum analysis is used as the basis of design. Design utilizing the Equivalent Lateral Force Procedure is also illustrated as a prerequisite to design using the Dynamic Analysis Procedure. A key feature of this example that would be of particular interest to users is the design of reinforced concrete shear walls by the procedure in the 2014 edition of ACI 318 Building Code Requirements for Structural Concrete.
  2. Code Master - price Rp 160.000,- 
    This 6-page laminated reference guide provides an easy-to-follow 11-step procedure for seismic design in accordance with the 2018 IBC and ASCE 7-16, with emphasis on the seismic design of a typical one-to-three story building. Illustrations are provided for many of the difficult to understand requirements. Subjects addressed include determination of mapped spectral response accelerations; consideration of exceptions to the seismic code requirements; Seismic Design Category determination; consideration of plan and vertical structural irregularities; determination of seismic base shear, redundancy coefficient and seismic load effects; and compliance with drift control requirements.
  3. International Building Code 2018 - price Rp 1.000.000,-
    The hardcopy of the newest IBC 2018
