Qt is an open source, cross-platform development environment that is free for many uses. Please see the license. 1.2. Compilation 23 OpenSeesPy Documentation, Release 3.3.0.0 Dependency The purpose of this project is to create a package that will allow aspiring developers to get started on writing code without having to worry about the compilation environment. A program as large as OpenSees relies on many third- party libraries, often referred to as dependencies. It can be a daunting task assembling, compiling, and linking these libraries. Many times, these libraries depend on other libraries, and so on. The current list of dependencies includes: • MUMPS (5.1.2) • Scalapack (2.0.2.13) • UMFPACK (5.7.7) contained in Suite-Sparse (5.3.0) • SUPERLU (5.2.1) • SUPERLUMT (3.0) • SUPERLUDIST (5.1.0) • Openblas (0.3.5) • Parmetis (4.0.3) • ARPACK (3.6.3) • Libevent (2.1.8) • GCC(8.2.0) • TCL (8.6.9)** Tcl only • Python(3.7.2)** OpenSeesPy only Please ensure that your project complies with each library’s licensing requirements. Another feature of this build platform is modularity. Developers can select from a list of build options that can be turned on and off as required. The basic configuration builds the structural analysis core. Other build options include parallel processing, reliability, and the particle finite element method (PFEM) modules. Python and Tcl interpreters are additional build options. These options are located in single configuration file called qmake.conf. By default, the environment is configured to build the core along with the parallel processing module. Other options can be turned on by deleting the ‘#’symbol that precedes the option; this includes the option into the build environment.

Modelling of full 3D finite element (FE) geometry of such plates is not only uneconomical but often requires the use of complex software and advanced numerical knowledge. Therefore, numerical homogenization is an excellent tool, which can be easily employed to simplify a model, especially when accurate modelling is not necessary. Homogenization allows for simplifying a computational model and replacing a complicated composite structure with a homogeneous plate. Here, a numerical homogenization method based on strain energy equivalence is derived. Based on the method proposed, the structure of the prefabricated concrete slabs reinforced with steel spatial trusses is homogenized to a single plate element with an effective stiffness. There is a complete equivalence between the full 3D FE model built with solid elements combined with truss structural elements and the simplified Citation: Staszak, N.; Garbowski, T.; Szymczak-Graczyk, A.

  • Bridge Types in NSW Historical Overviews 2006
    Timber Truss Bridges Study of Relative Heritage Significance of All Timber Truss Road Bridges in NSW 1998 25 Historical Overview of Bridge Types in NSW: Extract from the Study of Relative Heritage Significance of all Timber Truss Road Bridges in NSW HISTORY OF TIMBER TRUSS BRIDGES IN NSW 1.1 GENERAL During the first fifty years of the colony of New South Wales, 1788 - 1838, settlement was confined to the narrow coastal strip between the Pacific Ocean and the Great Dividing Range. The scattered communities were well served by ships plying the east coast and its many navigable rivers. Figure 1.1a: Settlement of early colonial NSW. Shaded areas are settled. In Governor Macquarie's time between 1810-1822, a number of good roads were built, but despite his efforts and those of the subsequent Governors Darling and Bourke, and of road builders George Evans, William Cox and Thomas Mitchell, the road system and its associated bridges could only be described as primitive. Many roads and bridges were financed through public subscriptions or as private ventures, particularly where tolls could be levied. The first significant improvement to this situation occurred in late 1832 when Surveyor- General Mitchell observed a competent stone mason working on a wall in front of the Legislative Council Chambers in Macquarie Street. It was David LennoxR3. He was appointed Sub-Inspector of Roads on October 1, 1832 then Superintendent of Bridges on June 6, 1833. His first project was to span a gully for the newly formed Mitchell's Pass on the eastern side of the Blue Mountains.

  • Learning the Methods of Engineering Analysis Using Case Studies, Excel and VBA - Course Design
    Computers in Education, Session 1520 Learning the Methods of Engineering Analysis Using Case Studies, Excel and VBA - Course Design Michael A. Collura, Bouzid Aliane, Samuel Daniels, Jean Nocito-Gobel School of Engineering & Applied Science, University of New Haven Abstract Methods of Engineering Analysis, EAS 112, is a first year course in which engineering and applied science students learn how to apply a variety of computer analysis methods. The course uses a “problem-driven” approach in which case studies of typical engineering and science problems become the arena in which these analytical methods must be applied. A common spreadsheet program, such as Microsoft Excel, is the starting point to teach such topics as descriptive statistics, regression, interpolation, integration and solving sets of algebraic, differential and finite difference equations. Students are also introduced to programming fundamentals in the Visual Basic for Applications environment as they create the algorithms needed for the analysis. In this programming environment students gain an understanding of basic programming concepts, such as data types, assignment and conditional statements, logical and numerical functions, program flow control, passing parameters/returning values with functions and working with arrays. EAS 112 is a stop along the Multidisciplinary Engineering Foundation Spiral1 in the engineering programs at the University of New Haven. A typical student will take the course in the second semester of the first year. Certain engineering foundation topics will appear in the assigned problems and case studies, contributing to students’ understanding of areas such as electrical circuits, mass balances, and structural mechanics. At this point along the spiral curriculum students are given most of the equations needed to analyze the case study problems, but they are responsible for development of the algorithms and implementing these in the spreadsheet and/or programming environment.

  • Solaris Performance and Tools -- Chapter 3 Processes
    solarispod.book Page 35 Thursday, June 22, 2006 11:58 AM 3 Processes Contributions from Denis Sheahan Monitoring process activity is a routine task during the administration of sys- tems. Fortunately, a large number of tools examine process details, most of which make use of procfs. Many of these tools are suitable for troubleshooting applica- tion problems and for analyzing performance. 3.1 Tools for Process Analysis Since there are so many tools for process analysis, it can be helpful to group them into general categories. Overall status tools. The prstat command immediately provides a by-pro- cess indication of CPU and memory consumption. prstat can also fetch microstate accounting details and by-thread details. The original command for listing process status is ps, the output of which can be customized. Control tools. Various commands, such as pkill, pstop, prun and preap, control the state of a process. These commands can be used to repair applica- tion issues, especially runaway processes. Introspection tools. Numerous commands, such as pstack, pmap, pfiles, and pargs inspect process details. pmap and pfiles examine the memory and file resources of a process; pstack can view the stack backtrace of a pro- cess and its threads, providing a glimpse of which functions are currently running. 35 solarispod.book Page 36 Thursday, June 22, 2006 11:58 AM 36 Chapter 3 Processes Lock activity examination tools. Excessive lock activity and contention can be identified with the plockstat command and DTrace. Tracing tools. Tracing system calls and function calls provides the best insight into process behavior. Solaris provides tools including truss, apptrace, and dtrace to trace processes.

  • Evaluation of Smeared Constitutive Laws for Tensile Concrete to Predict the Cracking of RC Beams Under Torsion with Smeared Truss Model
    materials Article Evaluation of Smeared Constitutive Laws for Tensile Concrete to Predict the Cracking of RC Beams under Torsion with Smeared Truss Model Mafalda Teixeira and Luís Bernardo * Centre of Materials and Building Technologies (C-MADE), Department of Civil Engineering and Architecture, University of Beira Interior, 6201-001 Covilhã, Portugal; [email protected] * Correspondence: [email protected] Abstract: In this study, the generalized softened variable angle truss-model (GSVATM) is used to predict the response of reinforced concrete (RC) beams under torsion at the early loading stages, namely the transition from the uncracked to the cracked stage. Being a 3-dimensional smeared truss model, the GSVATM must incorporate smeared constitutive laws for the materials, namely for the tensile concrete. Different smeared constitutive laws for tensile concrete can be found in the literature, which could lead to different predictions for the torsional response of RC beams at the earlier stages. Hence, the GSVATM is used to check several smeared constitutive laws for tensile concrete proposed in previous studies. The studied parameters are the cracking torque and the corresponding twist. The predictions of these parameters from the GSVATM are compared with the experimental results from several reported tests on RC beams under torsion. From the obtained results and the performed comparative analyses, one of the checked smeared constitutive laws for tensile concrete was found to lead to good predictions for the cracking torque of the RC beams regardless of the cross-section type (plain or hollow). Such a result could be useful to help with choosing the best constitutive laws to be Citation: Teixeira, M.; Bernardo, L.
