FEMA 451B - Topic15-5a, b and c - Advanced Analysis
This topic addresses structural analysis requirements in performance-based earthquake engineering. Such analysis must typically include a variety of nonlinear effects, both material and geometric. This topic provides an overview of nonlinear analysis methodologies.
•Basic modeling concepts
•Nonlinear static pushover analysis
•Nonlinear dynamic response history analysis
•Incremental nonlinear dynamic analysis
•Probabilistic approaches
This is a summary of the topics covered. It should be emphasized that this slide (third bullet) and subsequent slides use the terminology “Response History Analysis” instead of “Time History Analysis”. Response history is a more accurate description of what is being done. Analyzing the history of time makes little sense, whereas the history of the response of a structure is meaningful. Incremental Dynamic Analysis (IDA) is a relatively new approach that uses response history analyses in a systematic manner to assess the behavior of a structure subjected to a suite of ground motions. The structure is repeatedly analyzed for each motion scaled for gradually increasing intensities. For each intensity analyzed, certain damage measures are recorded and plotted against intensity to produce “IDA Curves”.
We will only briefly review the probabilistic approaches because the approach is quite new, and has not been fully formulated. We will describe the probabilistic approach used by FEMA 350, and the broader approach being suggested by PEER.

FEMA 451B - Topic 06 - Inelastic Behavior of Materials and Structures
This topic introduces the concepts of inelastic behavior, explains why the behavior is expected in seismic response, and shows how the inelastic behavior is incorporated into the NEHRP Recommended Provisions, ASCE7, and the International Building Code (IBC).
• Illustrates inelastic behavior of materials and structures
• Explains why inelastic response may be necessary
• Explains the “equal displacement “ concept
• Introduces the concept of inelastic design response spectra
• Explains how inelastic behavior is built into the NEHRP
Recommended Provisions and ASCE 7-05

FEMA 451B Topic 04 - Structural Dynamics of Linear Elastic MDOF Systems
This topic covers the analysis of multiple-degrees-of-freedom (MDOF) elastic systems. The basic purpose of this series of slides is to provide background on the development of the code-based equivalent lateral force (ELF) procedure and modal superposition analysis. The topic is limited to two-dimensional systems.

BridgeModeler is the common thread of the BridgeKey suite of programs for bridge engineering. BridgeModeler is a series of programs with a standard Windows Graphical User Interface (GUI), which can read, display, edit and write data files for all programs that operate under the BridgeKey program group. It provides the user with the ability to interactively create, view and modify three-dimensional numerical models of bridge members for the construction of a complete three-dimensional bridge model. BridgeModeler can also interactively define, view and modify bridge-loading conditions that may be applied to bridge structures. BridgeModeler performs the following functions:
Create new bridge models
Modify and update existing bridge models
Visually display and verify a bridge model
Visually display and verify applied loads
Generate input for various analysis programs
Analyze models using the LARS load rating engine.
Display graphically and textually analysis program results
BridgeModeler also provides an interface to all BridgeKey applications by use of its Import/Export functions.
BridgeAnalysis is part of the BridgeKey suite of programs for bridge engineering. At the current time, it allows for the standalone analysis of bridge data stored in AASHTOWare BARS or C.W. Beilfuss and Associates LARS formats. Lateral Load Analysis data can also be processed. Future analysis engines may be incorporated in the future so that more types of data will be able to be analyzed through this one standard GUI. The BridgeAnalysis application gives the ability to create and modify data, run analysis on the data, and then view, save, and print the output.

if some body have the access to "nisee.berkeley.edu", it will be very helpful for me to get the report and full-size photos about El-Asnam Earthquake, Algeria, 10 october 1980.

Anybody can explain about what is the unit table output "center mass rigidity" at column " Mass X or Mass Y"on ETABs?
I was thinking why when I change the global unit kN-m to kN-mm it just different about 1000x, has it actually to be same or else?
And if we need the mass in unit tons, how to obtain from ETABs?
