Tools to Safeguard New Buildings and Assess Existing Ones
Nonlinear analysis methods such as static pushover are globally
considered a reliable tool 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.
Seismic Design Aids for Nonlinear Analysis of Reinforced
Concrete Structures simplifies the estimation of those vital
parameters. 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
incorrect assessment or interpretation.
Streamlined Analysis Using a Mathematical Model
To achieve a more accurate pushover analysis and improve general
performance-based design, this book reassesses some key inputs,
including axial force-bending moment yield interaction,
moment-curvature, and moment-rotation characteristics. It analyzes
these boundaries using a detailed mathematical model of reinforced
concrete sections based on international codes, and then proposes
design curves and tables derived from the authors studies using a
variety of nonlinear tools, computer programs, and software. The
text reviews relevant literature and describes mathematical
modeling, detailing numerical procedures step by step.
Including supplementary online material that can be used to
compute any parameter, this reference delineates nonlinear
properties of materials so that they can be used instantly for
seismic analysis without having to solve cumbersome equations.
