Bentley Systems Inc., the leading company dedicated to providing comprehensive software solutions for sustaining infrastructure, has released the 10.00.00.40 version HAMMER CONNECT Edition. This software demystifies the complex science of water hammer and transient analysis and puts the power to perform this critical work in your hands.
Every time a pump or valve is operated, potentially dangerous transients are introduced in your water distribution or wastewater system. Unchecked, transients can have catastrophic consequences on your pipes and equipment, operators, and customers.
Water utilities, municipalities, and engineering firms around the world trust HAMMER’s computationally rigorous engine and easy-to-use interface to efficiently identify, manage, and mitigate the risks associated with transients.
Identify critical points in the system that need protection and facilitate sound system design with HAMMER modeling tools:
- Focus on mitigating surge, not on the modeling process: Streamlined model building and management enables you to jump-start the model building process and manage your model effectively, so that you can focus on developing the most appropriate strategy for controlling and limiting hydraulic transients.
- Simulate transient precisely to improve the quality of your decisions: Decrease the risk of approximating the behavior of protective devices and rotating equipment. Rough estimation of transients can be too costly. HAMMER helps you accurately simulate the impact of a wide range of surge protection devices and rotating equipment (pumps and turbines).
- Leverage existing CAD and GIS data for improved design productivity and to enrich the system or model that utility personnel rely on.

This study proposes a seismic design optimization method for steel building frameworks following the capacity design principle. Currently, when a structural design employs an elastic analysis to evaluate structural demands, the analysis results can be used only for the design of fuse members, and the inelastic demands on non-fuse members have to be obtained by hand calculations. Also, the elastic-analysis-based design method is unable to warrant a fully valid seismic design since the evaluation tool cannot always capture the true inelastic behaviour of a structure. The proposed method is to overcome these shortcomings by adopting the most sophisticated nonlinear dynamic procedure, i.e., Nonlinear Time- (or Response-) History Analysis as the evaluation tool for seismic demands.
The proposed optimal design formulation includes three objectives: the minimum weight or cost of the seismic force resisting system, the minimum seismic input energy or potential earthquake damage and the maximum hysteretic energy ratio of fuse members. The explicit design constraints include the plastic rotation limits on individual frame members and the inter-story drift limits on the overall performance of the structure. Strength designs of each member are treated as implicit constraints through considering both geometric and material nonlinearities of the structure in the nonlinear dynamic analysis procedure. A multi-objective Genetic Algorithm is employed to search for the Pareto-optimal solutions.
The study provides design examples for moment resisting frames and eccentrically braced frames. In the examples some numerical strategies, such as integrating load and resistance factors in analysis, grouping design variables of a link and the beams outside the link, roundingoff the objective function values, are introduced. The design examples confirm that the proposed optimization formulation is able to conduct automated capacity design of steel frames. In particular, the third objective, to maximize the hysteretic energy ratio of fuse members, drives the optimization algorithm to search for design solutions with favorable plastic mechanisms, which is the essence of the capacity design principle.
For the proposed inelastic-analysis-based design method, the seismic performance factors (i.e., ductility- and overstrength-related force reduction factors) are no longer needed. Furthermore, problem-dependent capacity design requirements, such as strong-column-weak-beam for moment resisting frames, are not included in the design formulation. Thus, the proposed design method is general and applicable to various types of building frames.

Earth Pressures against- and Stability of Retaining Structures
30 ECTS thesis submitted in partial fulfillment of a Magister Scientiarum degree in Civil Engineering
Author(s): Sigurður Már Valsson Published By:University of Iceland Published Year:2011 Size: 8,93 MB Quality:Unspecified
Abstract:
The objective of the presented research is to investigate methods used to calculate earth pressures against- and the stability of retaining structures. The classical methods of calculating earth pressures are covered in detail. They are named after their creators Charles-Augustin de Coulomb and William John Macquorn Rankine. A special interest is taken in a variant of Rankine‟s theory developed at Norges teknisk- naturvitenskapelige universitet (NTNU) that incorporates cohesive properties of soils as well as roughness between the structure and the soil material. Both methods are then tested against each other in order to investigate if a clear link exists between the two. The methods are tested against proposed design values of earth pressure coefficients according to the design standard Eurocode 7. Håndbok 016 is a design handbook published by the Norwegian Road Administration (n. Statens vegvesen). In it is a chapter dedicated to the design of retaining structures and bridge abutments. The methods proposed to design retaining structures are used to design cantilevered structures of various heights and with various foundation- and backfill materials based on a few geometrical constraints. The structure designs created with methods in Håndbok 016 are modeled in the finite element program PLAXIS to test if the same material factors of safety could be derived that way. The results from this study are then discussed and commented upon.

Autodesk Inc., a world leader in 3D design software for entertainment, natural resources, manufacturing, engineering, construction, and civil infrastructure, announced the release of Structural Bridge Design 2017. This software helps engineers achieve greater flexibility and efficiency in the design of small-to medium-span bridges integrating loading, analysis, and code checking processes whist providing an efficient workflow.
This single integrated software solution does not require valuable time importing, exporting or converting data instead it provides tools to help accelerate project completion.
Structural Bridge Design refines design options faster with automated updates in a define-analyse-code check loop whenever parameters change.
Engineers can additionally improve accuracy and reliability by reviewing code check requirements with detailed “hand” calculation-style design sheets that are created will full formulae and code referencing.
With Structural Bridge Design, users can deliver design reports faster using more accurate, reliable, consistent and verifiable data throughout the project lifecycle. These reports provide an understanding of engineering calculations involved to help maintain consistency and context throughout the project lifecycle.
To provide better understanding, the software creates side-by-side graphical displays of the data and results produced in the reports at all stages of analysis and design to offer further understanding of the results.
The design sections and bridge beams that are available within the software are based on a variety of international standards – including Eurocodes, AASHTO LRFD, British Standards as well Australian and New Zealand Standards. This allows users to create and develop their small-to-medium span bridges using required international standards before construction has commenced.
The functionality of Structural Bridge Design software can be simply broken down into three specific areas including:
- Section plan which deals with design on a section by section basis
- Girder design which works with the whole length of the girder
- Bridge Structure loading and analysis
Employing Autodesk Structural Bridge Design on your business’s projects will allow you to save time and money by utilising the tools available within the software.
