What are the advantages of the tensile monolithic structure

A brief introduction to what is the tensile overall structure.

The components in the tensile monolithic structure include a compression rod that bears only pressure and a rope that bears only tension (tension).

1. It can give full play to the compressive resistance of the pressure rod and the tensile resistance of the cable, and can give full play to the performance of the material to greatly save the material.

2. Large stiffness changes can be achieved through small deformation, which has a good advantage in occasions that require variable stiffness.

3. It can be applied to the structure (aerospace deployable mast).

The mechanical analysis of the tensile monolithic structure is similar to the grid structure of the cable rod of the prestressed hinged joint, except for some special graphics, it contains internal mechanisms and presents geometric flexibility. For research purposes, in addition to the general form-finding and hydrodynamic analysis processes, an intermediate process is sometimes used: the study of stability, mechanism, and prestress states.

The analytical model of the tensile monolithic system must take into account the nonlinear properties and the existence of equilibrium self-supporting processes. Mohri illustrates how to ensure proper self-stress and the stiffness of the elements, and also gives an algorithm to identify the self-stress state consistent with the stiffness provided by the cable. A nonlinear analysis of the static properties of a tensile monolithic structure has been completed, and the model is based on the relaxation principle or the matrix catch-up principle of Newton-Raphson processes, and a dynamic relaxation model has also been made.

The structure of tensioning is oneBuilding structure, the invention of the famous American architect Fu (.

"Tensile" refers to the condensation of "tensile" and "integrity". The concept was inspired by nature. Fuller believed that the universe operates according to the principle of tensile consistency, i.e., gravitation.

It is a balanced web of tension, and the planets are isolated points in this web. According to this idea, the tensile monolithic structure can be defined as a self-supporting and self-stressed spatial grid structure composed of a group of discontinuous compression members and a set of continuous tension elements.

Precautions for tensioning:

1. The concrete strength of the tensioning front beam body must reach 90 according to the design requirements before it can be tensioned.

2. Carefully inspect and calibrate the anchors and tensioning tools before tensioning.

3. The two ends of the tension are used, and the oil pressure gauge is required to be as synchronous as possible and steadily apply stress so that the two tension ends are connected to each other (walkie-talkie.

4. Tension pump personnel must wear safety helmets.

and protective gear.

5. There should be obvious signs on the site, and personnel who have nothing to do with the work are strictly prohibited from entering.

6. Tension to anchorage.

When locked, jacks.

No one should stand behind to prevent the broken wire of the prestressed steel bar from popping out and injuring people.

The tensile structure consists only of a cable and a pressure bar. The compression rods are isolated and strictly separated in a continuous cable. These struts are connected by pre-stressing cables and do not require any external support or anchorage.

It is a method to form a tensile integral structure by using the element structure of stress self-equilibrium. For a long time, many scholars have explored this aspect, constructed various forms of unit structures, and spliced the unit structures into various forms of tensile overall structures.

Disadvantages: 1. The scope of use has certain limitations, when the number of prestressed pipes in the beam is large, the plate surface tension prestressed Changchun pipeline can not be staggered, and can only be used under the plate tensioning. 2. There are a large number of grooves on the floor, and the floor perception is poor during the construction process, and the effect of clear water floor cannot be achieved.

3. When the tension notch is closed, the concrete is resistant to pick-up and color difference, and there are obvious traces of repair. The structural floor of this project is designed with steel fiber reinforced concrete, which can cover the tension notch.
