CSI ETABS 2016 v16.2.0 build 1645 x86+x64
The innovative and revolutionary new ETABS is the ultimate integrated software package for the structural analysis and design of buildings. Incorporating 40 years of continuous research and development, this latest ETABS offers unmatched 3D object based modeling and visualization tools, blazingly fast linear and nonlinear analytical power, sophisticated and comprehensive design capabilities for a wide-range of materials, and insightful graphic displays, reports, and schematic drawings that allow users to quickly and easily decipher and understand analysis and design results.
From the start of design conception through the production of schematic drawings, ETABS integrates every aspect of the engineering design process. Creation of models has never been easier - intuitive drawing commands allow for the rapid generation of floor and elevation framing. CAD drawings can be converted directly into ETABS models or used as templates onto which ETABS objects may be overlaid. The state-of-the-art SAPFire 64-bit solver allows extremely large and complex models to be rapidly analyzed, and supports nonlinear modeling techniques such as construction sequencing and time effects (e.g., creep and shrinkage). Design of steel and concrete frames (with automated optimization), composite beams, composite columns, steel joists, and concrete and masonry shear walls is included, as is the capacity check for steel connections and base plates. Models may be realistically rendered, and all results can be shown directly on the structure. Comprehensive and customizable reports are available for all analysis and design output, and schematic construction drawings of framing plans, schedules, details, and cross-sections may be generated for concrete and steel structures.
ETABS provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises. Immensely capable, yet easy-to-use, has been the hallmark of ETABS since its introduction decades ago, and this latest release continues that tradition by providing engineers with the technologically-advanced, yet intuitive, software they require to be their most productive.

Lindo What'sBest! v15.0.1.0
What'sBest! is an add-in to Excel that allows you to build large scale optimization models in a free form layout within a spreadsheet. What'sBest! combines the proven power of Linear, Nonlinear (convex and nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Semi-Definite, Stochastic, and Integer optimization with Microsoft Excel -- the most popular and flexible business modeling environment in use today. The recently released What'sBest! 15.0 includes a number of significant enhancements and new features.
Enhancements to the Simplex solvers boost performance on linear models. Large models solve an average of 20% faster using primal simplex and 15% faster for dual simplex.
New symmetry detection capabilities dramatically reduce the time required to prove optimality on certain classes of models with integer variables. Performance has been improved on Markowitz portfolio problems with minimum buy quantities, and/or limit on number of instruments at nonzero level. Other enhancements provide faster solutions on certain task assignment-like models.
Stability and robustness of the Global solver has been improved through several enhancements to quadratic recognition and range reduction. Improved exploitation of convexity of certain ratio constraints, e.g., as found in heat exchanger network design problems.
Several new functions and constraint types are recognized, e.g., the =WBALLDIFF() All Different constraint, for general integer variables. The =WBALLDIFF() function allows one to specify a set of integer variables, such that each variable in the set must have a unique value, different from all other variables in the set. |

Dan Dubina, Viorel Ungureanu, Raffaele Landolfo - Design of Cold-formed Steel Structures
Eurocode 3: Design of Steel Structures
Part 1-3 – Design of Cold-formed Steel Structures
Wiley, 2012
pdf, 676 pages, english
ISBN: 978-3-433-02979-4
Following pioneering research in the 1940s, research into cold-formed steel intensified in the 1970s and led to numerous national European design specifications, and subsequently the preparation of Part 1-3 of Eurocode3 (EN1993-1-3) for cold-formed steel structures. Now a Euronorm, EN1993-1-3 is fully embedded in the Eurocode framework. This book serves as a reference text for design engineers using EN1993-1-3. It forms part of the suite of ECCS Eurocode Design Manuals prepared in recent years for other parts of EN1993 and other Eurocodes to aid the implementation of Eurocodes in European states. The book draws on the authors’ considerable experience with designing cold-formed steel structures, both as academics and practitioners, and strikes a balance between theory and practice. Applications of cold-formed steel have broadened over the years. Coldformed steel is now used as primary structural elements, as in steel framed residential buildings, steel storage racks, portal frames, and tubular truss and frame structures, and as secondary structural elements, as in roofing and wall systems featuring purlins, girts and corrugated steel sheeting. Additionally, integrated building systems have been developed, such as cassettes, as have stressed skin principles for designing the building envelope. The design of cold-formed steel is perceived to be challenging by many structural engineers because the thinness of the steel leads to buckling and failure modes not found in the design of hot-rolled and fabricated steel structures. Furthermore, roll-forming techniques have developed rapidly in recent decades and spawned highly optimised cross sections featuring intermediate stiffeners and complex lip stiffeners, which are not easily designed using conventional methods. The book covers the design of structural members of complex shapes and connections as well as the design of integrated structural solutions, such as cassettes, and design using stressed skin principles. The structural behaviour and design to EN1993-1-3 are explained and numerous worked examples are included to guide or enable a cross-check for structural design engineers. The final Chapter 8 deserves a special mention as it addresses the comprehensive range of considerations other than structural to be made in cold-formed steel construction, including thermal transmission and sound, serviceability, durability, sustainability and recyclability. Methods of design for single and multi-storey housing are explained in detail, concluding with a comprehensive worked example of a residential building. This book presents a landmark in the development of guidelines for the structural design of cold-formed steel. It is arguably the most extensive reference available for designing cold-formed steel structures to EN1993-1-3, and will serve the structural engineering community well in adapting to the expanding range of residential and industrial applications of cold-formed steel. |

Wiley, 2014
pdf, 926 pages, english
ISBN: 978-3-433-03107-0
The use of composite structures in construction is increasing. The optimized combination of the two materials concrete and steel produces particularly cost-efficient structures. This book presents a large number of numerical examples with detailed explanations of the provisions of Eurocode 4. It deals with the most common structural components in building construction: beams, columns and slabs. Furthermore, comprehensive chapters provide insight into the topics of creep and shrinkage, as well as fatigue. This book enables the reader to efficiently perform analyses of composite structures. It is a valuable reference book for professionals as well as an outstanding means for students to become familiar with the Eurocode 4. |
