Spatial objects are used to model non-structural secondary elements attached to the structure. These elements add no stiffness to the existing model. Loads applied to spatial objects are transferred to the structure through one or more attach joints. The loads are transferred using a “rigid plate” approach.
Concentrated, pressure and wind loads may be applied to spatial objects. The figures below shows a spatial object loaded vertically and horizontally attached to a cantilever column. Also, it shows the deformations and biaxial moments induced by the loads transferred by the spatial object.
The catenary cable element is a highly non-linear element used to model the catenary behavior of a cable suspended between two points under the effect of its self-weight. This formulation accounts for the non-linearity due to large displacements.
A cable has no bending, shear, compression or torsion stiffness. Due to this fact, the fixities at the ends are ignored; the cable is always treated as member acting in tension only. In the interface of the TSE, the user can create a catenary cable by associating a cable type section to a member.
Direct Analysis Method (DAM) available for AISC 360-16 and AISC 360-10 standards. The options for the Stability Design Method are Direct Analysis Method (DAM) and Effective Length Method (kL).
The TSE software considers restrained warping for the torsion of thin-wall open sections. Notice that this phenomenon is not included in most commonly used frame analysis programs. Almost all frame programs in practice use St-Venant torsion theory ignoring the effects of restrained warping.
The TSE software allows users to animate results from different types of analysis such as:
-Static Linear Analysis
-Static P-Delta Analysis
-Natural Frequencies Analysis
-Seismic and Dynamic 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.
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.
With the TSE software, users are able to animate various static linear and P-Delta analysis results such as the:
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.
Animating the envelopes helps minimizing the amount of information on the screen. The user can focus on the most critical regions of the model.

Functionalities of the TSE program allow to generate automatically detail elements in an automatically generated mesh perimeter.
These functionalities are specifically related to the refinement area, the opening, the linear constraint and the punctual constraint.
All detail elements added to the TSE model will be automatically connected to the finite element mesh.
The mesh perimeter will also connect any elements already in the model to the mesh perimeter automatically if they are in the plane of the mesh contour.
IFC (INDUSTRY FOUNDATION CLASSES)
The integration of IFC in the TSE program enables importation of models from a large number of architectural and structural software.
IFC (Industry Foundation Classes) is an open and neutral data format allowing the definition of related classes to all construction objects. It is dedicated to the building sector and aims to software interoperability (all editors, all applications).
IFC is the most widely used protocol for information exchange and sharing between different platforms of BIM (Building Information Modeling).
Established in 1986, SAFI strives to develop structural software solutions meeting the highest standards of the industry aiming to increase users’ productivity.
