Nonlinear analysis methods such as static pushover or limit analysis
until collapse are globally considered reliable tools for seismic and
structural assessment. But the accuracy of seismic capacity
estimates--which can prevent catastrophic loss of life and astronomical
damage repair costs--depends on the use of the correct basic input
parameters.
Tools to Safeguard New Buildings and Assess Existing Ones
Seismic Design Aids for Nonlinear Analysis of Reinforced Concrete
Structures simplifies the estimation of base structural parameters and
enables accurate evaluation of proper bounds for the safety factor. Many
design engineers make the relatively common mistake of using default
properties of materials as input to nonlinear analyses without realizing
that any minor variation in the nonlinear characteristics of
constitutive materials, such as concrete and steel, could result in a
solution error that leads to a disastrously incorrect assessment or
interpretation. To achieve a more accurate pushover analysis and improve
general performance-based design, this book:
-
Reviews relevant literature to help engineers conduct structural
seismic assessment
-
Includes design curves, alleviating the need for complex mathematics
-
Offers supplementary online tools to aid in computing any parameter
-
Provides complete computer coding used to obtain building collapse
multipliers
Reassessing key inputs, this book analyzes boundaries using a detailed
mathematical model based on international codes. It proposes design
curves and tables derived from the authors' studies, detailing modeling
numerical procedures step by step. The authors include analytical bounds
of the structural safety factor for some typical frames, making this
work a sound and valuable tool for assessment or desi
