ABSTRACT
Pushover analysis involves certain approximations and simplifications that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. In literature, some improved pushover procedures have been proposed to overcome the certain limitations of traditional pushover procedures.
The effects and the accuracy of invariant lateral load patterns utilised in pushover analysis to predict the behavior imposed on the structure due to randomly selected individual ground motions causing elastic and various levels of nonlinear response were evaluated in this study. For this purpose, pushover analyses using various invariant lateral load patterns and Modal Pushover Analysis were performed on reinforced concrete and steel moment resisting frames covering a broad range of fundamental periods. Certain response parameters predicted by each pushover procedure were compared with the 'exact' results obtained from nonlinear dynamic analysis. The primary observations from the study showed that the accuracy of the pushover results depends strongly on the load path, properties of the structure and the characteristics of the ground motion.
Pushover analyses were performed by both DRAIN-2DX and SAP2000. Similar pushover results were obtained from the two different softwares employed in the study provided that similar approach is used in modeling the nonlinear properties of members as well as their structural features.
The accuracy of approximate procedures utilised to estimate target displacement was also studied on frame structures. The accuracy of the predictions was observed to depend on the approximations involved in the theory of the procedures, structural properties and ground motion characteristics.

priPrinter is a printer driver that allows you to manipulate printer output before it is printed. priPrinter is installed and selected in the same way as other printer drivers. After printing it automatically displays print preview where you can preview your printings, change layout, reposition pages, crop them and many more. After that you print it to the real printer or save your document for later using. With priPrinter you always will be sure how your printings will look. You may measure items on the paper, define margins and pages layout. There is no need to print again and again trying to achieve desired placement.

The book advances the sate-of-the-art by not only documenting how to monitor the environment, but also referring the reader to other more detailed comprehensive books. This nicely illustrated book should be useful at the senior undergraduate level, as well as to students initiating graduate studies in environmental sciences.

A resource on vibration that imparts a deep physical as well as mathematical understanding is critical to students who first encounter the subject. Books with an overly mathematical focus can leave them without a grasp of the underlying physics and mechanics. Those that attempt to be reader-friendly often oversimplify the mathematics and mechanics, leaving them with a lack of depth and unprepared for advanced work and complex problems. With a carefully balanced approach, Engineering Vibrations provides a systematic and unified treatment of mechanical and structural vibrations along with rigorous yet approachable mathematical development.
This text advances abstract concepts from first principles. The author weaves together the physical interpretation and fundamental principles with applied problem solving and uses illustrative examples and case studies to reinforce the concepts, encourage effective interpretation of results, and assist in learning the techniques and procedures. Accompanied by more than 500 two- and three-dimensional drawings, the book offers tabulated results of case studies and a table of operators of various one-dimensional continua. It also contains problem-solving flowcharts for solving forced vibration problems for discrete and continuous systems. For each class of system, it explores the fundamental dynamics and studies free and forced vibrations under various conditions.
Buildinga solid understanding of the principles and bases for mechanical and structural vibration, Engineering Vibrations offers a comprehensive and accessible introduction to the subject of vibrations and progresses systematically to advanced topics.

for the needs of my work in the field of non-destructive testing of structures I'm searching for these standards:
1. ASTM C 876 - 09 Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete.
2. ASTM E797 / E797M - 10 Standard Practice for Measuring Thickness by Manual Ultrasonic Pulse-Echo Contact Method
Please, don't upload earlier editions, because I have them.
Thanks in advance.
