Reinforcement and formwork for complex shapes in Advance Concrete


Reinforcement and formwork for complex shapes in Advance ConcreteThe article describes how we can create reinforcement and formwork drawings for structures with a complex geometry, namely bridge abutment using Advance Concrete. The bridge abutment is a part of infrastructure which is created at the ends of the bridge in order to take the transmitted loads of the bridge superstructure and the supports of the access path to the bridge.

To define the chosen geometry, an ACIS block can be created or the complex geometry can be divided into several blocks having a simple geometry which can be assembled in order to obtain the initial model.

We chose the second method for reasons related to the flexibility of Advance Concrete while modeling volume elements.

How to create any 3D concrete shape

Reinforcement and formwork for complex shapes in Advance Concrete

Advance Concrete provides the creation of any 3D and 2D shapes. The predefined concrete shapes can be chosen from the library or new ones can be created. To add a new concrete shape it is enough to create a closed contour and then save the shape in the concrete library. These new shapes can then be used either in the current drawing or for other projects.

The created concrete elements are defined as beam and column structural elements. These are positioned one in regard to the other, composing the entire concrete ensemble.

 

How to obtain a 3D reinforcement cage for special concrete shapes

The reinforcement drawing is created by selecting all the concrete elements. In the created reinforcement drawing, sections are added through the specific concrete zones.

The definition bars are created in one section and then distributed in elevation or top view. Several types of bars (straight, U and L bars) and distributions (linear, variable, multiple and quantitative) are available for use. The most frequent reinforcement bars are polygonal and straight bars and linear and variable distributions. Concrete covers can be set for each leg of the polygonal bar.

The bar detailing and reinforcement symbols can be done both manually (they can be customized and saved in the reinforcement symbol library) and automatically.

The bars numbering and lists creation is automatically done. Sub-entity marks are assigned for variable distributions, emphasizing that the variable distribution belongs to a single shape definition bar.

The drawings are created according to standard STAS 438/1,3 -89. The drawing creation according to other standards is similar.

Formwork details

The formwork drawing is created by adding the desired sections and elevations for structural elements, assigning specific hatches and line weights. The dimensioning of sections is quickly done by adding intersection and level dimensions.

Layout and Print

The reinforcement and formwork drawings can be placed in any page format. Also the views can be grouped and the title block can be attached according to the chosen format.

Numbering of the reinforcement bars and lists can be done in layout mode. The drawings can be printed one by one or by selecting several from the available print window.

Test it yourself

We have shown a simple example of a formwork and reinforcement cage created for a complex shape of the structural element. If you want to see the model described above, please download the specific model and drawings from here or, as a pdf file from here.

The example was created in Advance Concrete 2013.

  1. Great article! That is the kind of information that should
    be shared across the internet. Shame on Google for no longer positioning this
    put up upper! Come on over and visit my site . Thanks
    =)
