This feature is especially useful for larger size floors. When a slip-joint is used, the bending moments along the joint will be zero, while there is a full transfer of the shear force. On the other hand, by using the Tributary Area method we assume that the entire load is applied on the transfer slab, ignoring the structure from above. And now they are ready to share their knowledge with you. It uses finite element analysis to analyse and design slabs of any shape with two-way action automatically considered. Slab-on-ground can be modelled using the simplified springs or using advanced soil-structure interaction. Perform a complete frequency analysis using SLB to evaluate mode shapes and associated frequencies of the slab floor plate.

This is expected since the load is larger and the transfer beam has increased stiffness, and therefore attracts larger internal forces.

Shear-free walls The walls in the model can be set to “Shear-free”, in order to simulate the pre-fabricated concrete panels, or load bearing masonry walls.

Vertical Deflections

Piles Piles can be modelled below the lowest floor when considering a slab on ground. Soil-Structure Interaction State-of-art analysis of slabs-on-ground, where the entire structure and the soil are analysed together, in order to obtain most reliable soil pressure and settlement results.

Perform a complete frequency analysis using SLB to evaluate mode shapes and associated frequencies of the slab floor plate. In the figure above Fig. For instance, if we imagine that the entire structure is propped and all the props are removed after the concrete is fully set, the static analysis will capture the structural behaviour adequately.


Finite Element Analysis

Basically the modelling approach or design assumptions will influence the evaluation of the loading on the transfer slab, and ultimately it will influence the entire design niducta the structural system. CAD Import and Modelling. Eurocode 2 and Eurocode 8 British standard: Slab-on-ground can be modelled using the simplified springs or using advanced soil-structure interaction. But if the props at each floor are removed before the floor above is constructed, the static analysis will not provide accurate results.

Forced Floor Vibrations SLB can be used to evaluate the time history of the displacement, velocity and acceleration due to a dynamic force applied at any point on the floor. CAD drawings that contain information in appropriate layers can be used to import the geometry of a complete floor in minutes. Software development Structural modeling and design Finite element analysis.

In this case the reaction in the transfer column point load on the transfer slab is reduced significantly, and the loading is distributed onto the surrounding columns. Freely model structures of any shape and orientation without specifying a working grid or creating beam inductaa.

This approach will produce the largest possible loading at the transfer column, at the expense of loading to the continuous columns.

The mid-span beam moment below the transfer column is also kept relatively large. The other challenge is considering the method of construction.

Model slabs of any shape. Behaviour of composite beam—column flush end-plate connections subjected to low-probability, high-consequence loading.

Beam and Band Beam Design Beams and Band beams can be defined in any direction within a model and are fully integrated in the 3D floor system. We refined our Finite Element Meshing algorithm so that it will support this type of irregular inducha geometries.


The increased axial stiffness of the columns will affect the lateral stability analysis. Model the soil using simplified springs Winkler model or using soil structure interaction in a linear elastic half-space to design slab-on-ground.

We will follow through a numerical example to illustrate the major points. In this case the reactions column loads will still be identical Fig. Finite element mesh is automatically generated to modelled structural elements without the need to manually specify mesh subdivisions.

Evaluation of the Transfer Floor Loading by Tributary Area Method Traditionally we may evaluate the loading on slans transfer floor by Tributary Area approach, ignoring the flexibility of the transfer slabs, and its influence on the load distribution.

Instead, we suggest that a very good understanding of slaba influence of the modelling assumptions and all input parameters on the final results is essential in order to analyse and design a transfer slab.
