ALLPLAN and SCIA Engineer

Working across different Solutions within the ALLPLAN brand, customers often encounter an inconsistent look and feel. This can leave customers with the impression that they are working with separate tools rather than a unified platform. With the introduction of a common title bar, we address this challenge directly. By establishing a unified, consistent design element across all major Solutions of ALLPLAN.

3D Wind Load Engine

Engineers and designers are increasingly challenged by the complexity and rigor of up-to-date wind load requirements for structures, especially as regulatory standards like ASCE evolve. Mistakes or outdated methods can result in costly design revisions, compliance risks, or even structural vulnerabilities. The new 3D Wind Load Engine solves these problems by automatically generating wind loads in complete accordance with ASCE 7-22—the latest U.S. code standard. With a single step, you can rapidly apply three-dimensional wind loads across your entire structure, removing the need for time-consuming manual modeling and reducing the risk of missing code updates.• Fast and easy application of wind loads on structures

• No need for time-consuming manual input
• Easy review of pressure coefficients and verification of applied surface loads
• In compliance with the latest US design code ASCE 7-22

Mobile Loads

When structures must withstand loads that can move or shift positions, such as traffic on bridges, cranes in industrial facilities, or crowds on slabs, many of our customers face the daunting challenge of managing an overwhelming number of load combinations. Analyzing these numerous scenarios not only consumes tremendous time but also increases the risk of missing critical worst-case situations, potentially leading to over-designed or unsafe structures. The Moving Loads feature directly addresses this complexity. By leveraging the robust principles of influence lines and surfaces, the tool automatically pinpoints the most critical positions for moving load systems before calculations even begin. This allows you to focus your analysis and post-processing efforts only on these select, worst-case scenarios—rather than sifting through a multitude of non-critical possibilities.

• Significant time-savings in case the structure is subject to moving load systems such as traffic on bridges, cranes in industrial facilities, crowds walking across slabs
• Easy and straightforward handling of the large number of load combinations resulting from the presence of moving load systems
• Automatic identification of the worst-case positions of the load system before running the calculation, avoiding computing negligible and non-critical load situations

Footfall Analysis

Many engineers face significant challenges when designing buildings with large open spaces, lightweight floors, or areas housing sensitive equipment. Vibrations caused by everyday human activities—like walking, running, or crowd movement—can lead to occupant discomfort, dissatisfied clients, or even operational problems for sensitive equipment. Traditionally, these vibration issues are discovered too late, often after construction, resulting in expensive retrofits, project delays, and increased reputational risk. Footfall Analysis empowers you to address these challenges head-on. By rigorously assessing a structure’s dynamic response—measuring key parameters such as acceleration, velocity, and Response Factor—and referencing industry standards (SCI P354, CCIP-016, and AISC DG11), you can identify and solve vibration problems early in the design phase.

• In-depth analysis of buildings with large open areas, footbridges and lightweight floors
• Calculating dynamic response to loads induced by human activity (walking, running, etc.)
• Eliminating vibrations that would lead to discomfort or operational problems
• Helping avoid costly modifications of buildings, bridges, etc. after construction

Beam Finite Elements accounting for warping (7th degree of freedom)

• In-dept analysis and safe and economical design of thin-walled or open-section beams and elements exposed to significant torsion
• Accurate modelling of slender or thin-walled beams, open-section beams, and structures subjected to significant torsion or complex loading
• Accurate predictions of stresses and deformations in cases where traditional beam (finite) elements are inadequate

Steel 2nd generation EN 1993-1-1 & EN 1993-1-3

In most of Europe, structures using cold formed steel need to be designed according to the rules described in EN 1993-1-3. An update of these rules will become mandatory in 2028, called the second generation of Eurocodes. The verifications for cold formed steel can be complex and tedious, especially if done by hand. With the automated code design for cold formed steel in SCIA Engineer the verifications with detailed output and formulas are just one click away, and now future proof with the second generation Eurocodes available as well.

External Tendons

Structural engineers working on prestressed and post-tensioned concrete structures face mounting challenges as demands for innovation, longer spans, and sustainable upgrades increase. Traditional internal reinforcement methods can limit both design flexibility and the ability to optimize or rehabilitate existing structures. The External Tendons feature empowers you to model, analyze, and optimize external (unbonded) tendons with unprecedented ease and precision, supporting both bridges and building structures - and accommodating unique geometric requirements, whether straight or curved, in any plane.

• Effective modelling of external tendons for beams, slabs, walls, and plates.
• Tendon paths, straight or curved, can be defined manually or imported from DWG/DXF files.
• Accurate simulation of tendon installation, tensioning, and grouting processes using staged analysis.
• Results include tendon profiles, stress distributions, prestress losses, and their impacts on the structure.

Punching Check Extension

SCIA Engineer 26 allows punching shear checks for any slab and subregion interacting with a wall or a column of any shape. Users can define control perimeters manually or use automatically generated ones for standard columns, with forces calculated according to EN 1992-1-1.

• Automatic control perimeters for standard columns
• User-defined control perimeters for non-standard columns, corners, and end walls
• Accurate design of reinforcement to resist local shear forces at supports
