STRUCTURAL ANALYSIS IN EARTHQUAKE ENGINEERING A BREAKTHROUGH OF SIMPLIFIED NON-LINEAR METHODS
info:
Structural response to strong earthquake ground motion cannot be accurately predicted due to
large uncertainties and the randomness of structural properties and ground motion parameters.
Consequently, excessive sophistication in structural analysis is not warranted. For the time
being, the most rational analysis and performance evaluation methods for practical
applications seem to be simplified non-linear procedures, which combine the non-linear static
(pushover) analysis of a relatively simple mathematical model and the response spectrum
approach. In recent years, a breakthrough of these procedures has been observed. They have
been implemented into the modern guidelines and codes. The paper discusses such
procedures. After a brief overview of the methods, the major attention is focused on the N2
method, which has been implemented into the recent draft of the Eurocode 8 standard. The
theoretical background of the extended version of the method, which can be applied for
asymmetric structures, is presented. The similarities and differences between different
methods, the determination of target displacement in the capacity spectrum method, the
problems related to the application of simplified methods to analysis of 3D models, the
approximations and limitations of the simplified inelastic methods, and the direct
displacement-based design are discussed. Although different methods may yield in many
cases similar results, they differ in respect to simplicity, transparency and clarity of theoretical
background. The most important difference is related to the determination of displacement
demand. The use is inelastic spectra is considered to be more appropriate than the use of
highly damped equivalent elastic spectra.

Broken Buildings, Busted Budgets: How to Fix America's Trillion-Dollar Construction Industry By Barry B. LePatner
Publisher: University Of Chicago Press 2007 | ISBN: 0226472671 | PDF | 1.7 MB
Across the nation, construction projects large and small—from hospitals to schools to simple home improvements—are spiraling out of control. Delays and cost overruns have come to seem “normal,†even as they drain our wallets and send our blood pressure skyrocketing. In Broken Buildings, Busted Budgets, prominent construction attorney Barry B. LePatner builds a powerful case for change in America’s sole remaining “mom and pop†industry—an industry that consumes $1.23 trillion and wastes at least $120 billion each year.
With three decades of experience representing clients that include eminent architects and engineers, as well as corporations, institutions, and developers, LePatner has firsthand knowledge of the bad management, ineffective supervision, and insufficient investment in technology that plagues the risk-averse construction industry. In an engaging and direct style, he here pinpoints the issues that underlie the industry’s woes while providing practical tips for anyone in the business of building, including advice on the precise language owners should use during contract negotiations.
Armed with Broken Buildings, Busted Budgets, everyone involved in the purchase or renovation of a building or any structure—from homeowners seeking to remodel to civic developers embarking on large-scale projects — has the information they need to change this antiquated industry, one project at a time.
“LePatner describes what is wrong with the current system and suggests ways that architects can help—by retaking their rightful place as master builders.â€â€”Fred A. Bernstein, Architect Magazine “Every now and then, a major construction project is completed on time and on budget. Everyone is amazed. . . . Barry LePatner thinks this exception should become the rule. . . . A swift kick to the construction industry.â€â€”James R. Hagerty, Wall Street Journal

Significant inclusions in the book are a chapter on management (including operation, maintenance, and evaluation) of canal irrigation in India, detailed environmental aspects for water resource projects, a note on interlinking of rivers in India, and design problems of hydraulic structures such as guide bunds, settling basins, etc.
The first chapter of the book introduces irrigation and deals with the need, development and environmental aspects of irrigation in India. The second chapter on hydrology deals with different aspects of surface water resource. Soil-water relationships have been dealt with in Chapter 3. Aspects related to ground water resource have been discussed in Chapter 4. Canal irrigation and its management aspects form the subject matter of Chapters 5 and 6. Behaviour of alluvial channels and design of stable channels have been included in Chapters 7 and 8, respectively. Concepts of surface and subsurface flows, as applicable to hydraulic structures, have been introduced in Chapter 9. Different types of canal structures have been discussed in Chapters 10, 11, and 13. Chapter 12 has been devoted to rivers and river training methods. After introducing planning aspects of water resource projects in Chapter 14, embankment dams, gravity dams and spillways have been dealt with, respectively, in Chapters 15, 16 and 17.
The students would find solved examples (including design problems) in the text, and unsolved exercises and the list of references given at the end of each chapter useful.

Capacity Demand Diagram Methods Based on Inelastic Design Spectrum
info:
An improved capacity-demand-diagram method that uses the well-known constant-ductility design spectrum for the demand diagram is developed and illustrated by examples. This method estimates the deformation of inelastic SDF systems consistent with the selected inelastic design spectrum, while retaining the attraction of graphical implementation of the ATC-40 Nonlinear Static Procedure. One version of the improved method is graphically similar to ATC-40 Procedure A whereas the second version is graphically similar to ATC-40 Procedure B. However, the improved procedures differ from ATC-40 procedures in one important sense. The demand diagram used is different: the constant-ductility demand diagram for inelastic systems in the improved procedure versus the elastic demand diagram in ATC-40 for equivalent linear systems. The improved method can be conveniently implemented numerically if its graphical features are not important to the user. Such a procedure, based on equations relating the yield strength reduction factor, Ry, and ductility factor, μ, for different period, Tn, ranges, has been presented, and illustrated by examples using three different Ry-μ-Tn relations...
Modal pushover analysis as a tool for evaluation and design of irregular frames
info:
This paper investigates the application of modal pushover analysis (MPA) as a tool to estimate seismic demands of
structures with irregular mass distribution. A set of 20 ground motions is selected and median peak values of interstory
drift ratios, story shears and overturning moments obtained with MPA are compared with results of nonlinear time
history analysis (NL-THA). It is concluded that modal pushover analysis can be used to estimate seismic demands for
practical applications in evaluation and design of frames with mass irregularity.
Keywords: Modal pushover; Mass irregularity; Pushover analysis; Nonlinear time history analysis; Higher modes;
Incremental dynamic analysis; Seismic response
An Incremental Response Spectrum Analysis Procedure Based on Inelastic Spectral Displacements for Multi-Mode Seismic Performance Evaluation
info:
The so-called Nonlinear Static Procedure (NSP) based on pushover analysis has been developed
in the last decade as a practical engineering tool to estimate the inelastic response quantities
in the framework of performance-based seismic evaluation of structures. However NSP suffers from
a major drawback in that it is restricted with a single-mode response and therefore the procedure can
be reliably applied only to the two-dimensional response of low-rise, regular buildings. Recognizing
the continuously intensifying use of the pushover-based NSP in the engineering practice, the present
paper attempts to develop a new pushover analysis procedure to cater for the multi-mode response
in a practical and theoretically consistent manner. The proposed Incremental Response Spectrum
Analysis (IRSA) procedure is based on the approximate development of the so-called modal capacity
diagrams, which are defined as the backbone curves of the modal hysteresis loops. Modal capacity
diagrams are used for the estimation of instantaneous modal inelastic spectral displacements in a
piecewise linear process called pushover-history analysis. It is illustrated through an example analysis
that the proposed IRSA procedure can estimate with a reasonable accuracy the peak inelastic
response quantities of interest, such as story drift ratios and plastic hinge rotations as well as the
story shears and overturning moments. A practical version of the procedure is also developed which
is based on the code-specified smooth response spectrum and the well-known equal displacement
rule.
