StruBIM Anchors ACI 318

As of this version, users can introduce the forces of the section instead of the forces of each anchor. The forces are those of the one-dimensional structural elements: axial, shear and bending moments in both directions and torsional moment.

In the case of plates level with the concrete element or on a layer of mortar, the program performs an iterative calculation, due to the non-linear behaviour of the materials, until the integration of the stresses in the section, given a deformation plane, coincides with the forces imposed by the metallic profile. The behaviour of the materials is as follows:

• Anchors
  Stress diagram - linear tensile deformation, with a modulus of elasticity of 210 GPa and null in compression (it is assumed they provide no compression resistance).
  
• Concrete and mortar
  Stress diagram - deformation with constant compression (AISC Steel Design Guide 1) with a value of 0.85fc (ACI 318-14 22.8.3.2) and null in tension.

As of the 2019.g version, an interface panel has been dedicated to create and edit anchorage plates and metal sections. As far as the plate is concerned, any geometry composed of a polygonal can be introduced, for which, users introduce its points. For design purposes, the plate is considered rigid. It can be level with the concrete, on a mortar filling or suspended from the anchors. In this last case the program distinguishes whether the anchors have a washer and base nut in contact with the concrete or not.

Furthermore, as of this version, users can introduce the metal section that is to be joined to the plate. It can be an I-section, circular hollow section or rectangular hollow section.
