To enhance productivity of GSE™ Timber software’ users, the Anchorage Elongation Method can be defined as variable (tension only) and variable (tension and compression). The anchorage slip is calculated at each iteration according to the tension efforts at the anchorage locations.
HSE™ users can efficiently set and edit all required fatigue parameters for the structure allowing to consider all applicable fatigue loads such as Galloping, Natural Wind Gust, or Truck-Induced Gust.
The live load reduction is available for the GSE™ steel, concrete, aluminum, and wood modules. The live load reduction will be applied to the columns of the structure.
Live loads can be automatically reduced according to the selected method. The software computes the live load reduction factor (LLRF) that will reduce the effective axial compression force in columns.

The resistance limit states, under fire conditions, are calculated for large cross-section wood elements. To improve the productivity of GSE users, the elements cross-sections are automatically reduced during the limit state checks.

To improve productivity of GSE Timber users, a new type of wood shearwall anchorage has been added. Continuous Tie Down Systems and their effects on the shearwall properties are now available in the GSE software. Standard libraries of continuous tie down rods are also readily available.
Concrete buildings are widely used in the construction industry. In such structures, slabs are key structural elements resisting the gravity and live loads of each floor.

The vibration limit state is now calculated for sawn lumber floor joists. To improve the productivity of GSE users, the floor joists are automatically generated inside the truss load surfaces.

In previous versions, member displacements were displayed only along the section’s principal axes. With the latest update, users can now also visualize deflections along the straight axes – offering greater flexibility and clarity in analysis results.
This new feature allows users to quickly define various types of loads on all the plate elements present in the selected perimeters.
The soil-structure interaction is an important component in the design of a building or any structure in general. In order to enhance productivity of GSE users, an automatic slab on grade generation function is available.

It is important to note that the torsional stiffness of an open section is function of the warping end conditions as well as the location of the torsional load. Thus, the distribution of the forces in the structure having members resisting torsion may differ whether this option is enabled or disabled.
The punching shear analysis is directly linked to any joints that has been defined as a slab support of type column in the concrete tab of a joint properties. By defining the geometrical properties of a slab supporting joint, the program will determine the shear perimeter around the support.
The latest revision of the GSE STEEL DESIGN enables structural steel designers to design cold-formed steel members based on the North American specification for the design of cold-formed steel structural members covering Canada (CSA S136-16), the United States and Mexico (AISI S100-16).
