simdesign.rcmrf.bdim.tr_7599.column

This module provides the column class implementation for the tr_7599 design class in the BDIM layer.

class simdesign.rcmrf.bdim.tr_7599.column.DesignTableTR[source]

Bases: object

Design table class for Turkish design practice.

It is used for longitudinal reinforcement area calculation in reinforced concrete rectangular column sections.

Variables:

data (Dict[str, Dict[str, npt.NDArray[np.float64]]]) – Dictionary containing reinforcement for varying steel grades and axial load ratios.

data: Dict[str, Dict[str, ndarray[tuple[Any, ...], dtype[float64]]]]
get_reinforcement(Nd, Mxd, Myd, fcd, fsyd, fsyk, bx, by)[source]

Retrieve reinforcement area from design tables with interpolation.

Parameters:

  • Nd (float) – Axial load on the RC column (kN).

  • Mxd (float) – Bending moment on the RC column in the X direction (kNm).

  • Myd (float) – Bending moment on the RC column in the Y direction (kNm).

  • fcd (float) – Design value of concrete strength (kPa).

  • fsyd (float) – Design value of steel strength (kPa).

  • fsyk (float) – Characteristic value of steel strength (kPa).

  • bx (float) – Breadth (width) along global X (m).

  • by (float) – Breadth (width) along global Y (m).

Returns:

Required longitudinal reinforcement area of bars distributed along -x and -y on each side.

Return type:

Tuple[float, float]

Notes

The design tables are created assuming rebars are evenly spaced.

simdesign.rcmrf.bdim.tr_7599.column.ECONOMIC_MU: float = 0.25

Maximum mu value considered for the economic column design.

simdesign.rcmrf.bdim.tr_7599.column.MAX_NIU = 0.6

Maximum allowed value of axial load ratio. Based on Section 8.2.6 in TS500-1984.

simdesign.rcmrf.bdim.tr_7599.column.table = <simdesign.rcmrf.bdim.tr_7599.column.DesignTableTR object>

Design table data class used for computing required reinforcement area.

class simdesign.rcmrf.bdim.tr_7599.column.Column(line, section, gamma_rc)[source]

Bases: ColumnBase

Column implementation for design class tr_7599.

This class extends ColumnBase by narrowing the attribute types and overriding design methods per TBEC-1975 and TS500-1984.

Variables:

  • steel (Steel) – Steel material assigned to the column.

  • concrete (Concrete) – Concrete material assigned to the column.

  • MIN_B_SQUARE (float) – The default minimum square column dimension.

  • MIN_B_RECTANGLE (float) – The default minimum rectangular column dimension.

Parameters:

  • line (Line)

  • section (Literal[1, 2])

  • gamma_rc (float)
