Bases: object

This is a class to represent a reinforced concrete beam. It creates an object for the reinforced concrete beam on which design is to be performed as per the guidelines stated by user.

Parameters:

  • width (int/float) – A handle to the PyRCD.RCbeam.rcb that detects the width of the reinforced concrete beam in millimeters (mm).

  • depth (int/float) – A handle to the PyRCD.RCbeam.rcb that detects the effective depth of the reinforced concrete beam in millimeters (mm).

  • length (int/float) – A handle to the PyRCD.RCbeam.rcb that detects the clear length of the reinforced concrete beam in meters (m).

  • bending_moment (int/float/list) – A handle to the PyRCD.RCbeam.rcb that detects the bending moment on the reinforced concrete beam in kilo-newton-meters (kNm). If the instance is int or float, it is considered as bending moment is only acting at center of the beam and zero moment at the beam’s end. If the instance is list, list must represents bending moment at left end, center and right end of the beam with three elements repectively.

  • shear_force (int/float/list) – A handle to the PyRCD.RCbeam.rcb that detects the shear forces on the reinforced concrete beam in kilo-newton (kN). If the instance is int or float, the shear force value is considered as same on either end of the beam. If the instance is list, list must represents shear force at left end, center and right end of the beam with three elements repectively.

  • torsion (int/float, optional) – A handle to the PyRCD.RCbeam.rcb that detects the torsion on the reinforced concrete beam in kilo-newton-meter (kNm). This instance is to be used when user intend to design beam with torsion. Default is None, no torsion is considered.

  • defl (int/float, optional) – A handle to the PyRCD.RCbeam.rcb that detects the maximum deflection of the reinforced concrete beam in millimeters (mm). This instance is to be used when user intend to check the deflection limit of the beam. By Default beam is considered safe in deflection.

  • cover (int/float, optional) – A handle to the PyRCD.RCbeam.rcb that detects the effective cover that is to be provided in beam in millimeter (mm), default is 25mm. This instance is to be used when user intend to change the effective cover of the beam. Check InputExample:Nodes Details for more details.

  • ast_provided (int/float/list) – A handle to the PyRCD.RCbeam.rcb that detects the reinforcement area provided by user in the reinforced concrete beam in square-millimeter (mm2). If the instance is int or float, it is considered as reinforcement has only been provided in the bottom of the beam. If the instance is list, list must represents rebar areas provided at left end, center and right end of the beam repectively. Check InputExample:Nodes Details for more details.

  • left_support_size (int/float, optional) – A handle to the PyRCD.RCbeam.rcb that detects width of support size on left end of the beam in mllimeter (mm), default is 400 mm. This instance is used to perform detailing of the beam. Check InputExample:Nodes Details for more details.

  • right_support_size (int/float, optional) – A handle to the PyRCD.RCbeam.rcb that detects width of support size on right end of the beam in mllimeter (mm), default is 400 mm. This instance is used to perform detailing of the beam. Check InputExample:Nodes Details for more details.

  • left_end_continous (boolean, optional) – A handle to the PyRCD.RCbeam.rcb that detects wheather the beam is continous on the left end or not. Default is False (i.e. Beam is not continous). This instance is used to perform practical detailing of the beam. Check InputExample:Nodes Details for more details.

  • right_end_continous (boolean, optionall) – A handle to the PyRCD.RCbeam.rcb that detects wheather the beam is continous on the right end or not. Default is False (i.e. Beam is not continous). This instance is used to perform practical detailing of the beam. Check InputExample:Nodes Details for more details.
