Qué incluye el cálculo de uniones en estructuras metálicas?

El cálculo de uniones incluye el dimensionado técnico de las conexiones entre perfiles metálicos (pilar-viga, viga-viga, viga-correa), considerando los esfuerzos reales del proyecto (cargas permanentes, variables y dinámicas). En Jansa Metal diseñamos principalmente uniones articuladas atornilladas, optimizadas para facilitar el montaje en obra y permitir futuros desmontajes o ampliaciones sin afectar la estructura.

¿Qué ventajas tienen las uniones atornilladas sobre las soldadas?

Las uniones atornilladas ofrecen varias ventajas sobre las uniones soldadas en estructura metálica: - Rapidez en el montaje: Las uniones atornilladas permiten una instalación más rápida y sencilla. - Facilidad de desmontaje: Son ideales para estructuras temporales o que requieren modificaciones futuras. - Calidad y seguridad: Reducen el riesgo de errores durante el montaje y garantizan una conexión segura y fiable. - Menor dependencia de condiciones climáticas: A diferencia de la soldadura, que puede verse afectada por las condiciones del entorno, las uniones atornilladas son más consistentes.

¿Qué consideraciones deben tenerse en cuenta al diseñar uniones estructurales?

Al diseñar uniones estructurales, es crucial considerar: - Tipo de carga: Las uniones deben ser capaces de soportar las cargas aplicadas, ya sean estáticas o dinámicas. - Materiales: El tipo de material utilizado influye en la elección del tipo de unión. - Accesibilidad: Las uniones deben ser accesibles para inspección y mantenimiento. - Normativas y estándares: Es importante cumplir con las normativas y estándares vigentes para asegurar la seguridad y calidad de la estructura.

¿Qué son las uniones semirrígidas y cuándo se utilizan?

Las uniones semirrígidas proporcionan una rigidez intermedia entre las uniones rígidas y las articuladas. Se utilizan cuando se requiere cierta flexibilidad en la estructura sin comprometer significativamente la rigidez. Estas uniones son comunes en edificios que necesitan absorber deformaciones y movimientos sin sufrir daños estructurales.

How do we do it?

How we approach connection and weld calculations

Technical analysis of the project: We study applied loads (self-weight, wind, snow, dynamic), materials, and the type of structure.

Selection of connection type: We choose the most suitable type: fixed, semi-rigid, pinned, or welded, depending on the project’s requirements.

Application of standards: All our calculations comply with the CTE (Spanish Technical Building Code), Eurocode, and specific regulations according to use and structural typology.

Delivery of technical documentation: Detailed drawings, bolt or weld specifications, and full calculations ready for execution.

We also perform welded connection calculations for metal structures.

If your project requires welded connections, we calculate and optimize them based on the forces to be transmitted, weld type, thickness, and geometric configuration.

FAQ’s

What does the calculation of connections in metal structures include?

Connection calculation includes the technical sizing of joints between metal profiles (column-beam, beam-beam, beam-purlin), taking into account the actual forces of the project (permanent, variable, and dynamic loads). At Jansa Metal, we primarily design bolted pinned connections, optimized to facilitate on-site assembly and allow future disassembly or extensions without affecting the structure.

What advantages do bolted connections have over welded ones?

Bolted joints offer several advantages over welded joints in metal structures:

– Faster assembly: Bolted joints allow quicker and easier installation.
– Ease of disassembly: Ideal for temporary structures or those requiring future modifications.
– Quality and safety: Reduce the risk of errors during assembly and ensure a secure, reliable connection.
– Less weather dependence: Unlike welding, which may be affected by environmental conditions, bolted joints offer more consistent results.

What considerations must be taken into account when designing structural connections?

When designing structural connections, it is essential to consider:
– Type of load: Connections must withstand applied loads, whether static or dynamic.
– Materials: The material type influences the choice of connection system.
– Accessibility: Connections should be accessible for inspection and maintenance.
– Codes and standards: Compliance with applicable regulations is essential to ensure the structure’s safety and quality.

What are semi-rigid connections and when are they used?

Semi-rigid connections offer intermediate stiffness between rigid and pinned joints.
They are used when some flexibility is required without significantly compromising rigidity. These joints are common in buildings that must absorb deformations and movements without suffering structural damage.
