NONLINEAR ANALYSIS OF MULTISTORY STRUCTURES USING NONLIN
Author: Gordon Chan | Size: 1.8 MB | Format:PDF | Quality:Unspecified | Publisher: February 24, 2005 Blacksburg, Virginia | pages: 143
This thesis presents the results of a study of the effect of variations of systemic parameters on the structural response of multistory structures subjected to Incremental Dynamic Analysis. A five-story building was used in this study. Three models were used to represent buildings located in Berkeley, CA, New York, NY, and Charleston, SC. The systemic parameters studied are post- yield stiffness, degrading stiffness and degrading strength. A set of single-record IDA curves was obtained for each systemic parameter. Two ground motions were used in this study to generate the single-record IDA curves. These ground motions were scaled to the design spectral acceleration prior to the applications. The effect of vertical acceleration was examined in this analysis. “NONLIN”, a program capable of performing nonlinear dynamic analysis, was updated to perform most of the analysis in this study. The damage measure used in this study was the maximum interstory drift. Some trends were observed for the post-yield stiffness and the degrading strength. However, no trend was observed for the degrading stiffness.

Fiber-reinforced polymer (FRP) composites have become an integral part of the construction industry because of their versatility, enhanced durability and resistance to fatigue and corrosion, high strength-to-weight ratio, accelerated construction, and lower maintenance and life-cycle costs. Advanced FRP composite materials are also emerging for a wide range of civil infrastructure applications. These include everything from bridge decks, bridge strengthening and repairs, and seismic retrofit to marine waterfront structures and sustainable, energy-efficient housing. The International Handbook of FRP Composites in Civil Engineering brings together a wealth of information on advances in materials, techniques, practices, nondestructive testing, and structural health monitoring of FRP composites, specifically for civil infrastructure.
With a focus on professional applications, the handbook supplies design guidelines and standards of practice from around the world. It also includes helpful design formulas, tables, and charts to provide immediate answers to common questions. Organized into seven parts, the handbook covers:
-FRP fundamentals, including history, codes and standards, manufacturing, materials, mechanics, and life-cycle costs
-Bridge deck applications and the critical topic of connection design for FRP structural members
-External reinforcement for rehabilitation, including the strengthening of reinforced concrete, masonry, wood, and metallic structures
-FRP composites for the reinforcement of concrete structures, including material characteristics, design procedures, and quality assurance–quality control (QA/QC) issues
-Hybrid FRP composite systems, with an emphasis on design, construction, QA/QC, and repair
-Quality control, quality assurance, and evaluation using nondestructive testing, and in-service monitoring using structural health monitoring of FRP composites, including smart composites that can actively sense and respond to the environment and internal states
-FRP-related books, journals, conference proceedings, organizations, and research sources

FGI Guidelines for Design and Construction of Health Care Facilities 2010
Author: The Facility Guidelines Institute | Size: 7.9 MB | Format:PDF | Quality:Original preprint | Publisher: The Facility Guidelines Institute | Year: 2010 | pages: 450 | ISBN: 9780872588592
On picking up the 2010 edition, users of previous editions of the Guidelines will notice a new organization to the content. This edition has been reorganized to reflect the numbering system of other national codes and stan- dards that design professionals and owners use every day. In addition, for clarity, full paragraph references are used in the text, including the chapter number followed by a hyphen and a sequenced number for each paragraph.
What will also be very noticeable is the new Part 6. For the 2010 edition, the Facility Guidelines Institute has partnered with the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., by adopting ANSI/ASHRAE/ASHE Standard 170: Ventila- tion of Health Care Facilities as the principal standard for ventilation systems in health care facilities. The 2010 edition of the Guidelines incorporates as Part 6 the 2008 edition of Standard 170, plus all addenda, present and future, issued by ASHRAE. Users can find an explanation of the relationship between ventilation information in the Guidelines text and in Standard 170, as well as information for accessing the Standard 170 addenda, at the beginning of Part 6.
The content of this edition is arranged in six Parts, grouping similar facility types together:
• Part 1 (General) provides information applicable to all health care projects and facility types.
• Part 2 (Hospitals) contains all of the chapters on hospitals.
• Part 3 (Ambulatory Care Facilities) contains chapters on a wide variety of outpatient facility types.
• Part 4 (Residential Health Care Facilities) includes chapters on residential care facilities—nursing, hospice, and assisted living.
• Part 5 (Other Health Care Facilities) contains chapters on other health care facility types that do not fall into the categories of Parts 2, 3, or 4. In this edition they are mobile, transportable, and relocatable units; freestanding birth centers; and adult day health care facilities.
• Part 6 (Ventilation of Health Care Facilities) contains ANSI/ASHRAE/ASHE Standard 170, as discussed above.

Lecture Notes: Nonlinear Earthquake Response Analysis of Reinforced Concrete Buildings
Author: Professor Shunsuke Otani | Size: 20 MB | Format:PDF | Quality:Original preprint | Publisher: University of Tokyo | Year: 2002 | pages: 432
Preface
This note is intended to introduce the state of the art in the nonlinear response analysis of reinforced concrete building structures under earthquake excitation to graduate students. The state of the knowledge on the behavior of reinforced concrete members and structures and the art of nonlinear response analysis are far form an established state. Therefore, this note will not provide any unique solution to a problem. The note was initially prepared for a special lecture on “nonlinear analysis of reinforced concrete buildings” at Department of Civil Engineering, University of Canterbury, New Zealand, from February to April, 1994. The note has been revised for use in Department of Architecture, University of Tokyo since 1996; this course was given in English. The note was extensively revised for a series of lectures on “nonlinear earthquake response analysis of reinforced concrete buildings” at European School for Advanced Studies in Reduction of Seismic Risk, Universita degli Studi di Pavia, Italy, from February to March, 2002.

Research and Applications in Structural Engineering, Mechanics and Computation contains the Proceedings of the Fifth International Conference on Structural Engineering, Mechanics and Computation (SEMC 2013, Cape Town, South Africa, 2-4 September 2013). Over 420 papers are featured. Many topics are covered, but the contributions may be seen to fall into one of four broad themes of the conference, namely: (i) structural mechanics (dynamics, vibration, seismic response, statics, bifurcation, buckling, stability, impact response, contact mechanics, fluid-structure interaction, soil-structure interaction, etc); (ii) mechanics of materials (elasticity, plasticity, fracture, damage, fatigue, creep, shrinkage, etc); (iii) modelling and testing (finite-element modelling, numerical methods, numerical simulations, experimental methods, experimental testing); (iv) structural-engineering practice (planning, analysis, design, construction, maintenance, repair, retrofitting, decommissioning). Not only do the considerations cover many types of engineering structures (buildings, bridges, tunnels, towers, space frames, roofs, foundations, shells, plates, mechanical assemblies, etc), they also span a diversity of engineering materials ranging from the traditional to the novel: steel, concrete, timber, masonry, aluminium, special alloys, glass, composites, functionally-graded materials, smart materials, etc.

Structural Design of Masonry is intended to be a source of technical information for designers, builders, contractors, code officials, architects, and engineers: indeed, anyone involved with the business of masonry construction. Numerous sources, references, and technical experts have been consulted during its preparation.
The ability to solve structural design problems is a prime requisite for the success of any engineer and/or architect. To facilitate development of this ability, a collection of example problems accompanied by a series of practical solutions and structural engineering methodologies is included herein. These examples place special emphasis on detailed structural design of any portions of conventional structures for which masonry may be the designated material.

The book covers the application of numerical methods to reinforced concrete structures. To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement. These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states.
The book gives a compact review of finite element and other numerical methods. The key to these methods is through a proper description of material behavior. Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond. These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells. This includes prestressing of structures, cracking, nonlinear stress-strain relations, creeping, shrinkage and temperature changes.
Appropriate methods are developed for each structural type. Dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage. Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language. The ConFem source code together with the problem data is available under open source rules in combination with this book.
The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers.

I want to buy a Video Card for my new PC. The APU(Core i5 4440) has an integrated Graphic chipset, HD 4600.
Is this graphic card (HD 4600) enough for smooth run of CSI Software? How about Autodesk software such as Robot Structural Analysis and also Tekla Structure v20?
If this VGA is not recommended for above software, please advise a discrete VGA card.
