SLAB ENGINEERING

REINFORCED CONCRETE SLAB DESIGN ASSISTANT

SAFI’s reinforced concrete slab design assistant becomes the ultimate tool for slab design in a simple and intuitive way. Part of the GSE Concrete Design , it allows the user to quickly and efficiently generate design strips for any concrete slab.

The reinforced concrete slab design assistant allows the user to quickly generate the design strips of a concrete slab. The assistant generates column strips and middle strips that are adapted to the geometries of the bidirectional span of the slab. This assistant is directly linked to the automated mesh generation functionalities, allowing us to use the geometrical elements such as supports, walls and openings for both the finite elements model and the design strips generation. 

 

Directly linked to the automated functionalities of the line of integration using finite elements, this application allows the user to operate in a specialized environment in order to perform mesh generation. SLAB ENGINEERING simultaneously defines model geometric elements such as supports, walls and openings.

The assistant generates column strips and middle strips that are adapted to the geometries of the bidirectional span of the slab. This assistant is directly linked to the automated mesh generation functionalities, allowing us to use the geometrical elements such as supports, walls and openings for both the finite elements model and the design strips generation.

Slab Engineering supports a complete and efficient solution for slab design. Without a doubt, this new technological breakthrough will help increasing productivity and success in various design projects.

Automated generation of the design strip

Once all the column lines are defined into the model, it is possible to use the automated generation of the design strip. This command will automatically generate integration lines representing the design strip adapted to the geometry of column lines for the slab. Further information on the use of integration lines is available in the technical document on this topic.

 

The column lines are used to determine the overall geometry of the bidirectional bay in the slab. These bays are detected by having a rectangular shaped bay closed between two X horizontal column lines and two Y vertical column lines. It is possible to have multiple supports present along one span. The four sides of a bay need to be indicated with a column line in order to allow the proper detection of a bidirectional bay.

The width of the column strip is calculated as the quarter of the shorter of the two spans of a bi-directional bay. In the case where a bay is not perfectly symmetrical, the shortest side of the bay will be considered. If one of the column strips is not completely parallel with the reinforcement axis of the slab, its width will be adjusted to the absolute width on both sides of the strip, as illustrated below. The more inclined the strip will be, the wider it will be adjusted. The middle strip is the space available between two column strips, hence the user only has to manage the width of the two surrounding column strips.

Welcome to SAFI's Technical News Board. Stay up to date as our leading experts share the latest developments in Structural Engineering.

ANIMATION FEATURE

Introducing the animation feature in SAFI. The next release of SAFI will now allow the user to animate results from different types of analysis such as:

-Static Linear Analysis
-Static P-Delta Analysis
-Buckling Analysis
-Natural Frequencies Analysis
-Seismic and Dynamic Analysis

STATIC LINEAR AND P-DELTA ANALYSIS

In the latest version of SAFI, the user is now able to animate various static linear
and P-Delta analysis results
such as the:
-Structure displacements
-Internal forces
-Stresses
-Support reactions.

Tower linear and buckling analysis

The results are scaled by a linearly increasing factor until the unity factor is reached. The user can detect which parts of the model undergo the most displacements or internal forces by seeing the variation of intensity across the model.

Animating the envelopes helps minimizing the amount of information on the screen. The user can focus on the most critical regions of the model.

ANIMATION FOR A BRIDGE MODEL

In the bridge results menu, animating the envelopes helps minimizing the amount of information on the screen. The user can focus on the most solicited regions of the model. As the animation evolves, the final results are displayed and the global envelopes are displayed.

FREQUENCY & BUCKLING

The frequency and buckling analysis provide multiple mode shapes describing multiple behaviors of the structure. With large models, the animation is helpful to discern and understand the mode shapes. It is easier to determine if the buckling mode is a local or global phenomenon. It also provides a very accurate interpretation of the participating mass of each mode in a seismic spectral analysis.

TIME HISTORY

The animation function displays every saved time-step to provide an accurate representation of the displacements, velocities, accelerations and internal forces acting on the structure.

This will provide the user a better understanding of the structure behavior during the dynamic event, such as finding the critical time of the dynamic loading.
