Do you want to perform earthquake analyses according to design codes or just in order to verify your structure? The current article describes in great detail two different approaches; the static (response specter) and the transient approach
Earthquake analyses can be performed by applying different procedures. The most popular procedure is the Response Spectrum analysis (RS-analysis). The RS-analysis is cheap to use in terms of numerical costs as it is based on modal results. However, the spectrum solution can only show positive results, i.e. positive stresses and strains, as it only records the maximum amplitudes for each mode and the superposition of these results in turn will give the positive results.
Another procedure is to perform a full transient analysis of the earthquake. Such analyses are computational expensive. However, they will give results based on the dynamic equation of equilibrium and hence both positive (tensile) and negative (compressive) stress results will be reported for the full length of the earthquake. In this tutorial a shell structure will be used to show how such analysis can be run in ANSYS Workbench.

The primary objective of this project was to develop a manual, for consideration and adoption by AASHTO, that provides step-by-step procedures for the following:
1. Assessing the condition of reinforced concrete bridge superstructure elements subjected to corrosion-induced deterioration.
2. Predicting the remaining service life of such elements.
3. Quantifying the service life extension for such elements expected from alternative maintenance and repair options.
The scope of work for this project was limited to bridge superstructure elements reinforced with black reinforcing steel and, to some extent, epoxy-coated reinforcing steel. It did not include prestressed concrete elements and other modified steels.
This manual is targeted toward engineers and maintenance personnel charged with maintaining the bridge structures.
This manual can be used by state and other highway agencies and adopted with or without modifications as guidelines for use within the organization.

This major textbook provides comprehensive coverage of the analytical tools required to determine the dynamic response of structures. The topics covered include: formulation of the equations of motion for single- as well as multi-degree-of-freedom discrete systems using the principles of both vector mechanics and analytical mechanics; free vibration response; determination of frequencies and mode shapes; forced vibration response to harmonic and general forcing functions; dynamic analysis of continuous systems;and wave propagation analysis.
The key assets of the book include comprehensive coverage of both the traditional and state-of-the-art numerical techniques of response analysis, such as the analysis by numerical integration of the equations of motion and analysis through frequency domain. The large number of illustrative examples and exercise problems are of great assistance in improving clarity and enhancing reader comprehension.

Various approaches to good construction practices that could improve the installation of transmission line structure foundations are presented. Spread foundations, drilled shaft foundations, pile foundations, and anchors are treated. This guide is intended to be used as a reference source for those involved in the ownership, design, and construction of transmission structures.

Engaging students and teaching students to think critically isnt easy! The new Ninth Edition of Halliday Resnick and Walker (HRW) has been strategically revised to conquer this challenge. Every aspect of this revision is focused on engaging students, supporting critical thinking and moving students to the next level physics understanding. Key to the ninth editions support for critical thinking and development of understanding physics concepts is Jearl Walkers modern voice. Jearl Walker is both an active teacher, who understands the challenges faced in todays classroom, and a world renown communicator of science to the general public. His Flying Circus material is integrated throughout the ninth edition to catch students attention, engage them, and encourage them to solve the underlying real world physics phenomenon and concepts, before they begin the more quantitative portion of the content or problem. New features in WileyPLUS are designed to help students read and come more prepared to class and to engage their various learning styles, as well as to help instructors make more efficient use of their class preparation time. HRW 9e provides the perfect solution for teaching a 2 or 3 semester calc-based physics course providing instructors with a tool by which they can teach students how to effectively read scientific material, identify fundamental concepts, reason through scientific questions, and solve quantitative problems.
