Modeling of Masonry Infill Panels for Structural Analysis
A.M. Reinhorn, A. Madan, R.E. Valles, Y. Reichmann and J.B.Mander
NCEER-95-0018 | 12/8/1995 | 96 pages |
A smooth hysteretic model based on an equivalent strut approach is proposed for masonry infill panels to be used in nonlinear analysis of building structures. The hysteretic model furnishes a versatile and robust simulation tool for representing masonry infill panels. The model, which is applicable for degrading ‘pinching’ elements in general, can be implemented to replicate a wide range of hysteretic force-displacement behavior resulting from different design and geometry by varying the control parameters of the model. The control parameters of the proposed hysteretic model can be determined using any suitable theoretical model for masonry infills. The report presents the development of the proposed hysteretic model. An available theoretical model for masonry infilled frames is recommended for estimating the control parameters of the proposed hysteretic rule. The methodology for calibrating the hysteretic model parameters is described. The hysteretic model is incorporated in the structural analysis program, IDARC2D Version 4.0, for quasi-static cyclic and dynamic analysis of masonry infilled frames. Simulations of experimental force-deformation behavior of prototype infill frame subassemblages are performed to validate the proposed model and presented herein. A lightly reinforced concrete frame structure is analyzed for strong ground motions to evaluate the influence of masonry infill panels on the response.

Book Description:
These time-honored manuals provide the tried-and-true information you need for making the most thorough and accurate labor and cost estimates in the most efficient manner. The hundreds of man-hour tables in these manuals are the product of hundreds of time and method studies conducted in the field and in the shop. As a result, these respected manuals and their tables provide you with a dependable, proven basis for obtaining production efficiency percentages by applying all known local conditions and variables. These manuals also allow you to obtain direct labor rates for the crafts involved. In short, you’ll be able to make accurate, reliable estimates anytime and anywhere with complete confidence. Computers are wonderful tools, solving problems as no human can. But construction estimating is not only a science and a craft, it is an art. The field-tested information in the Estimator’s Man-Hour Library is designed for those who understand that.

Finite Element Model Updating Using Computational Intelligence Techniques (Applications to Structural Dynamics) - Marwala, Tshilidzi
Finite element models (FEMs) are widely used to understand the dynamic behaviour of various systems. FEM updating allows FEMs to be tuned better to reflect measured data and may be conducted using two different statistical frameworks: the maximum likelihood approach and Bayesian approaches. Finite Element Model Updating Using Computational Intelligence Techniques applies both strategies to the field of structural mechanics, an area vital for aerospace, civil and mechanical engineering. Vibration data is used for the updating process. Following an introduction a number of computational intelligence techniques to facilitate the updating process are proposed; they include: • multi-layer perceptron neural networks for real-time FEM updating; • particle swarm and genetic-algorithm-based optimization methods to accommodate the demands of global versus local optimization models; • simulated annealing to put the methodologies into a sound statistical basis; and • response surface methods and expectation maximization algorithms to demonstrate how FEM updating can be performed in a cost-effective manner; and to help manage computational complexity. Based on these methods, the most appropriate updated FEM is selected using the Bayesian approach, a problem that traditional FEM updating has not addressed. This is found to incorporate engineering judgment into finite elements systematically through the formulations of prior distributions. Throughout the text, case studies, specifically designed to demonstrate the special principles are included. These serve to test the viability of the new approaches in FEM updating. Finite Element Model Updating Using Computational Intelligence Techniques analyses the state of the art in FEM updating critically and based on these findings, identifies new research directions, making it of interest to researchers in strucural dynamics and practising engineers using FEMs. Graduate students of mechanical, aerospace and civil engineering will also find the text instructive.

Google SketchUp for Site Design: A Guide to Modeling Site Plans, Terrain and Architecture
[img][/img]
This book describes SketchUp Process Modeling, a methodology for working with SketchUp. This approach provides a step-by-step road map that will show you how to use the tools and functions to construct expressive models of exterior spaces and architecture. The process addresses three main areas of instruction: drafting, modeling order, and organization. Mastering these skills will allow you to create models that are highly detailed and articulate, easy to work with, optimized for computer performance, and organized.
Figs. 1-1 through 1-3 and Figs. 1-8 through 1-13 are examples of site plans and architectural projects created using SketchUp Process Modeling.

The exercises presented in the following chapters are designed to completely familiarize you with every aspect of SketchUp itself. Here is the chapter layout:
2. Basics: Short exercises on each of the drawing and manipulation tools (Line, Arc, Push/Pull, Protractor, Axes, etc.)
3. Intersect and Follow Me: These tools are often used together, so they get their own chapter.
4. Multiple Copy: Exercises on rows of copied objects, linear arrays, and angular (rotated) arrays.
5. Roofs: Everyone works with them, and they can sometimes get tricky. SketchUp enables you to create, modify, and resolve roofs easily.
6. Groups and Components: Groups are used to make a collection of objects that act as one object. This is useful for isolating geometry, and to keep things from sticking to one another. Components enable you to insert external objects into your model and use
them multiple times. This is equivalent to external references used in other CAD packages.
7. Materials: Applying materials, colors, and textures to faces to enhance the display of your model.
8. Sectioning: Using section planes to cut into your model, to look inside, create floor plans, or produce a drawing to export to CAD.
9. Presentation: Usage of the walk-through tools, layers, pages (views) tour guide (slide show) and shadows.
10. Sandbox: Tools for creating and modifying TIN surfaces, used in terrain modeling.
11. Exact Dimensions: While SketchUp’s strength lies is its simple, non-rigid modeling ability, you can also use it like a standard CAD application by working with known measurements. This chapter shows ways to specify exact values when using any tool.
12. Tips and Tricks: Exercises that show handy ways to solve typical problems.
13. In Depth Exercises: Two exercise that combine many of the concepts presented throughout this book. One exercise results in a steel building frame created from structural shapes that were saved as components. The second exercise is to create a simple log cabin.
14. Program Settings: General knowledge of the display tools, preferences, keyboard shortcuts, and import/export.
15. Ruby Script: Some basics on how to use Ruby programming to create macros.
