 Geometric Model

The geometric model is immediately generated, thanks to the powerful wizard functionality. All its properties can be edited directly from the 3D environment of the software.

Computational model

The software generate automatically the computational model. They are generated geometric computational elements of solid type (quad).

Barrel Vault Input

It is possible to input barrel vaults with a rectangular plan shape, both with equal or different rise and ray with elliptic or parabolic shapes.
A linearly variable thickness can be defined between the base and the key zone of the vault. It is also possible to model the presence of the base piers with variable height, width and thickness; moreover, it is possible to locate openings in the piers.

It is possible to insert lateral ribbed arches: the thickness of this may be different from the vault. These can be created using the wizard steps and modified from the main program environment.

Reinforcing elements, such as rods, may be added consequently to the model, in the main input window.

Output - load curves F-U and Cb-U

For each performed analysis shows the load curve Strength - Displacement, with reference to the control point. You can save output data in xls file.

Cross Vault Input

Cross vaults with both rectangular and irregular plans may be defined.
In the first case it is necessary to simply input the size of the two sides of the rectangle, while in the most generic case  the length of the four sides and the length of one of the diagonals must be set. The geometry is completed by means of the input of the rise with respect to the center point and the thickness law

The possibility to model ribbing arches along the perimeter and in correspondence of the diagonals, aligned to the extrados of the vault or in correspondence of the median surface, is also available.

Finally piers at the four vertices of the vault with generic width and height may also be considered.

Reinforcing elements such as truss may be also added to the model from the main input environment.

You can view the computational model of the vault in both extruded form and non extruded.

Domical Vault Input

Domical vaults on a rectangular plan are considered. The geometry is defined by assigning the plan size and the rise. The width of the base piers and the length of the perimetral arches may also be customize.

It`s possible to model the piers, with variable width and height, at the four vertices of the vault.

The thickness of the vault can be set linearly variable between the base and the key zone.

The thickness of the vault can be set linearly variable between the base and the key zone.

In the property panel on the right you can read the characteristics of the selected item.

Cloister Vault Input

Cloister vaults on rectangular plans are considered. The geometry is defined by assigning the plan size and the  maximum rise at the intersection of four fans. The thickness of the vault can be set linearly variable between the base and the key zone.

Perimeter walls with variable thickness and height may be considered; these walls can be then customized by considering rectangular openings.

In the 3D environment it is possible to input tie-beam by means of a completely generic way: for example, it is possible to input tie-beams at the base of the vault or in the top of the walls.

Input Roofed cloister vault

Roofed cloister vaults on rectangular plans may be considered. The geometry is assigned through the introduction of the plan size and the rise with respect to the base level. The thickness of the vault can be set linearly variable between the base and the key zone.

Perimeter walls with variable thickness and height may be considered; these walls can be then customized by considering rectangular openings.

In the 3D environment it is possible to input tie-beam by means of a completely generic way: for example, it is possible to input tie-beams at the base of the vault or in the top of the walls.

The response is show in terms of  collapse mechanism, stress and strain at each step of the analysis.

Dome Vault Input

This wizard allows to model domes on circular or elliptical plans by defining the two main rays and its height.

A hole may be left at its top in order to consider the presence of a roof lantern. The hole is obtained by the intersection of the average surface area of the dome with a horizontal plane; therefore its radius is required.

The drums of the dome and that relative to the lantern may be considered, the latter also surmounted by a dome to complete the lantern. In both drums an arbitrary number of openings arranged radially along the perimeter of the vault, with generic width and height.

In the main environment mono-dimensional elements (with zero compressive strength) may be considered aiming at the simulation of reinforcing rings along the parallels of the dome.

Fiber reinforcements Module

Fiber reinforcements module, allows you to model reinforcement of arches and vaults with fiber-reinforced composite materials (FRP).

It`s possible to apply the reinforcement both on the intrados, and on the extrados, of any curved surface.
The model allows you to capture both the broken fibers, the effect of delamination.
You can model FRP reinforcements in their real disposal.
HiStrA allows to evaluate, in an accurate, the effects of the reinforcements on the collapse mechanism and, therefore, on the overall strength of the structure.
