Estructuras BIMparables con Bentley STAAD&RAM

Como ingenieros del sector AEC, hemos observado la adopciĆ³n generalizada de modelos de informaciĆ³n de construcciĆ³n (BIM). Durante los Ćŗltimos cinco aƱos, un nuevo tĆ©rmino, gemelo digital de infraestructura, ha ido ocupando un lugar central. ĀæCuĆ”l es la diferencia entre BIM y un gemelo digital de infraestructura? Como ingenieros estructurales utilizamos software para crear modelos 3D para anĆ”lisis y diseƱo, entonces, Āæestamos creando BIM o gemelos digitales de infraestructura? BIM es una capacidad de visualizaciĆ³n estĆ”tica empleada durante las fases de diseƱo y construcciĆ³n de un edificio. BIM integra todas las disciplinas en un modelo basado en CAD. El propĆ³sito de un BIM es permitir la colaboraciĆ³n entre disciplinas y visualizar restricciones espaciales. BIM sirve como datos fundamentales utilizados para crear un gemelo digital de infraestructura. Por ejemplo, su modelo de anĆ”lisis estructural 3D se puede exportar y traducir al formato CAD para usarlo en BIM. Un gemelo digital de infraestructura es una representaciĆ³n virtual de una entidad del mundo real, sincronizada con una frecuencia y fidelidad especĆ­ficas. Los datos en tiempo real de los sensores y el Internet de las cosas (IoT) estĆ”n vinculados al modelo digital preciso conforme a obra. El gemelo digital de infraestructura sirve como centro

BIMpressive Structures with STAAD & RAM

As engineers in the architecture, engineering, and construction (AEC) sector, we have observed the widespread adoption of building information modeling (BIM). Over the past five years, the term ā€œinfrastructure digital twinā€ has taken center stage. What is the difference between BIM and an infrastructure digital twin? As structural engineers, we use software to create 3D models for analysis and designā€”so are we creating BIMs or infrastructure digital twins? BIM is a static visualization capability employed during the design and construction phases of a building. BIM integrates all disciplines into a CAD-based model. The purpose of BIM is to enable collaboration between disciplines and visualize spatial constraints. BIM serves as foundational data used to create an infrastructure digital twin. For example, your 3D structural analysis model can be exported and translated into a CAD format for use in BIM. An infrastructure digital twin is a virtual representation of a real-world entity, synchronized at a specified frequency and fidelity. Real-time data from sensors and the Internet of Things (IoT) are linked to the accurate as-built digital model. The infrastructure digital twin serves as the smart building hub for owners and operators to schedule maintenance and ensure that the building is operating optimally.

Better Foundations for a Better Canada – Optimizing Designs with Canadian A23.3 2019 Codes

In the ever-evolving structural engineering landscape, ensuring that the foundations of our designs stay strong is the only way to ensure lasting infrastructure. As the Canadian infrastructure and innovation landscape continues to strengthen, engineers are being challenged more than ever to deliver projects quickly and cost-effectivelyā€“all without sacrificing quality of design. In this piece, we will demonstrate how foundation design can be optimized through the STAAD product workflow, with a spotlight on the incorporation of the Canadian A23.3 2019 Code. Designing through our fully interoperable STAAD.Pro and STAAD Foundation Advanced programs guarantees a complete project workflow. Canadian building codes are revised every few years, and Bentley aims to keep our preprogrammed codes as current as possible. STAAD Foundation Advanced uses Canadian code CSA A23.3:19 for the design and analysis of isolated footings, combined footings, pile caps, mat foundations, and other foundation elements. A complete structure and foundation design workflow can be established between STAAD.Pro and STAAD Foundation Advanced. These programs are powerful and versatileā€“an ideal combination for companies that want the ability to tackle a variety of projects. The load combinations applied in your structural analyses can vary, and it is important to have control over the factors that you

Dam Safety in an Earthquake

An earthquake can cause a dam to crack or dislocate, or even cause its component blocks to detach. The damage can result in uncontrolled water release or a catastrophic flood. Numerical methods such as finite element analysis play an important role in assessing the possible seismic damage to dams. In this blog post, we show how ADINA was used by a team of engineers in Switzerland for this challenging task.

Pulsating Moving Load in STAAD CONNECT Edition

This content delves into the fascinating subject of pulsating moving loads on bridges, flyovers, and similar structures. Also known as dynamic moving loads, these forces are generated by the periodic vertical force of moving vehicle wheels, caused by an unbalanced mass. This unbalanced mass can be caused by a number of factors, such as uneven weight distribution within the vehicle, or a defect in the wheel itself. Structural analysis software like STAAD is widely used to simulate the static response of moving loads on structures. However, simulating the dynamic effects of pulsating moving loads is not as straightforward. The video expertly guides you through the process of using STAAD’s time history feature to simulate the dynamic response of a structure to a pulsating moving load. The video guides a step-by-step explanation of how to effectively use the time history feature in STAAD. From understanding the parameters that must be considered when setting up the simulation, such as speed and frequency of the load, to interpreting and analyzing the results of the simulation to gain proper understanding of the dynamic behavior of the structure under the applied load. Overall, the video offers a comprehensive and engaging look into the complex subject

Steady State Analysis for Variable Input Frequency in STAAD

Every structure has its own unique natural frequency exhibited while disturbed by some external dynamic force. The external dynamic force can be harmonic or non-harmonic. If that forcing function is harmonic with the exciting frequency and close to the natural frequency of the structure, a resonance-like event could arise, which is catastrophic and undesirable for the overall structural performance. This type of harmonic excitation is exhibited mostly by the rotating machine. Say for example, a rotating machine is sitting on the foundation structure, then the designer needs to ensure that the resonance event is properly captured in the analysis, and this dynamic amplification is taken care of in the foundation design. In this type of situation, the harmonic excitation leads to the steady state problem where the transient part is discarded. However, in reality, the machine foundation is subjected to the variable range of the operating frequency. When the machine starts with zero frequency until it attains the maximum speed with highest frequency, the foundation experiences the spectrum of input frequencies. The interest of the engineer is to capture the moment the resonance can be expected, hence the steady state analysis for the variable frequency is required. The video content

Multiple Response Spectrum Curves With Different Damping Properties in STAAD

Each material has unique damping properties. If you want to analyze a structure composed of both steel and concrete you will have two different RS data with different damping properties for each material.Ā  For example the first floor of a building is made of concrete and the floors above are made of steel. You can set different damping values for each material, but the RS curve to be used would only have a single damping value. To solve this you can define two different RS data pairs with unique damping properties for each material and assign them to their respective elements for analysis. This video will walk you through the procedure to define multiple RS data sets with different damping properties and instruct the program to analyze a structure with multiple damping properties. https://youtu.be/cdVg-TlvRLQ Related ArticlesĀ  STAAD Learning Path
