This second edition of this book, Nonlinear Random Vibration: Analytical Techniques and Applications, expands on the original edition with additional detailed steps in various places in the text. It is a first systematic presentation on the subject. It covers Markovian and non-Markovian solutions of nonlinear stochastic differential equations, exact solutions of Fokker-Planck-Kolmogorov equations, methods of statistical linearization, statistical nonlinearization techniques, methods of stochastic averaging, truncated hierarchy techniques, and an appendix on probability theory.
This spreadsheet, which I write using Excel VBA, generates Response Spectrum from the recorded EQ data using NEWMARK`S LINEAR ACCELERATION and INTRPOLATION EXITATION METHODS.

Can anyone help with getting the following paper?:
Astaneh-Asl, A., Bergsma, G., and Shen, J. H. (1992). Behavior and Design of Base Plates for Gravity, Wind and Seismic Loads. Proceedings of the National Steel Construction Conference
I hate to say this, but I have gotten 2 warnings back to back few weeks ago.
It is without saying that the warnings I've received were due to violation of one rule.
At the first time I received, I thought I violated other rule than the one that I did, so I repeated my mistake.
Hence, my suggestion is, when you describe which rule a user violate, use the rule number instead of description. Then, refer to the rule page. Personally, I think it's more logical to direct to the rule page instead of describing what user did wrong.

Soil nail walls are a widely used technology for retaining vertical and nearly vertical cuts in soil. A significant portion of the cost of soil nail wall construction is related to the construction of a reinforced concrete face. The potential for use of a flexible facing design for soil nail walls to replace reinforced concrete facing was evaluated using three-dimensional finite difference modeling and physical testing of a 1.5 meter by 1.5 meter unit cell of a soil nail wall in clay. A steel mesh form of flexible facing was used as a substitute for concrete. The finite difference model predicted large vertical and horizontal deformations for surcharges of approximately 5 psi. In the physical testing, the flexible facing products performed well with regard to strength, but the facing experienced large vertical and horizontal deformations that were consistent with the numerical modeling. Based on these results, it is recommended that use of flexible facing as a substitute for reinforced concrete be limited to non-critical structures where large vertical and horizontal deformations are acceptable.

Folder Guard® is a powerful computer security program that you can use to control access to files, folders, and other Windows resources, such as Control Panel, Start Menu, and so on. You can use Folder Guard to lock your personal files and folders with passwords, to stop other users from peeking into your records. You can even completely hide your private folders from virtually all applications, and such folders would remain invisible until you enter a valid password. You can also protect sensitive system files from modification or destruction, disable access to the removable drives, restrict access to Control Panel, and more.

Equivalent Beam Method for Trusses,
Practice Periodical on Structural Design and Construction
Giltner, B. and Kassimali, A. (2000). ”Equivalent Beam Method for Trusses.” Pract. Period. Struct. Des. Constr., 5(2), 70–77.
Elasticity, plasticity, damage mechanics and cracking are all phenomena that determine the resistance of solids to deformation and fracture. The authors of this book discuss a modern method of mathematically modeling the behavior of macroscopic volume elements. The first three chapters review physical mechanisms at the microstructural level, thermodynamics of irreversible processes, mechanics of continuous media, and the classification of the behavior of solids. The rest of the book is devoted to the modeling of different types of material behavior. In each case the authors present characteristic data for numerous materials, and discuss the physics underlying the phenomena together with methods for the numerical analysis of the resulting equations
