Checking and Ratio

Checking¬†results Once the calculation for the structure is performed, we can check if the selected components (membrane, cables, pipes, etc.) are correct. That is to say, if its¬†resistance and behavior is acceptable.WinTess performs this operation, and displays the results by the button¬†Ratio¬†on the left or the menu¬†Graphics | Ratio. ¬† Membrane type bars Membrane type…

Safety Factors

From¬†version 3,117¬†, WinTess introduces a new way to apply the safety factors to the structures.NOTE: Although this method is much more versatile and is better suited to the modern normative, if preferred, the user can ignore it and continue to calculate as it was before the version 3,117. Window of safety factors is seen above.¬†The¬†coefficients…

Prestress

Basic concepts The membrane structures are constructed by providing a pretensioning force to membrane. The reasons for the prestressing are several: Self¬†weight of the membrane would deform it, forming unforeseeable wrinkles and making her exposed to uncontrolled movements. Considering¬†that the membranes can only withstand tension, if we put¬†it a tensioned state, when there are loads…

Pressure

Basic concepts In inflatable structures, they can be supported by air (large covered spaces of which membrane is hold in place by the overpressure of the interior with respect to the outside) or in the form of pneumatic structural elements inflated to pressures much higher than the previous ones like arches, bars, etc. . WinTess3…

Snow

Basic concepts In those cases where a tensile structure is situated in an area where it snows regularly, snow load is usually greater than the wind load and could become a real problem for the structure. The different regulations usually set a constant snow load for the different areas and different altitudes in each country.…

Wind

Basic Concepts The¬†wind¬†is one of the most important actions to be taken into account in a lightweight tensile structure. Except those which are placed in interior in a decorative way, we always consider the action of wind. In some areas of the World, this action is of vital importance, while in others¬†it¬†can go to second…

Point Loads

Basic concepts Tensioned structures without¬†membrane surfaces are achieved through wire mesh, such as an aviary. In the absence of membrane, if we wish to apply snow or wind (which are very small but not non-existent), we should apply directly at¬†nodes in WinTess3. We can also apply other loads due to objects that we hang from…

Results

In the state of analysis, once having arrived or not the state of balance of the structure, the most normal thing is to evaluate the results. The fastest way to get an idea is through the¬†Ratio¬†option, which can be accessed¬†via the menu¬†Graphics | Ratio¬†or¬†Ratio button¬†on¬†the left. However, if we want numerical results, we must go…

Integrated Calculation

Introduction In both engineering and architecture, it is common to find complex structures¬†that are formed by various¬†types ¬†of structural elements: walls, bars (pillars and beams), slabs, membranes, cables, etc. To address these structures, regardless of done by hand or with the help of computer programs, ¬†we usually break down the structure into¬†simple substructures, i.e. a…
