SECTION PROPERTIES ACCORDING TO THE STRAIGHT AXES
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.
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 GSE 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 GSE 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.
With the GSE 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.
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.
Animating the envelopes helps minimizing the amount of information on the screen. The user can focus on the most critical regions of the model.
