Concrete Shear Wall Calculator

The shear wall calculator completes strength and detailing checks based on the selected design standard.

For the ACI version the design checks are based on Chapter 11 of ACI-318 2019. Specifically the ACI-318 concrete wall calculation completes the following checks:

• Compression Check: Checks the axial strength of the shear wall subjected to compressive force to ACI-318 Clause 22.4.2
• Tension Check: Checks the axial strength of the shear wall subjected to tension force to ACI-318 Clause 22.4.3
• In-Plane Shear Check: Checks the in-plane shear strength of the shear wall subjected to lateral loads to ACI-318 Clause 11.5.4
• Detailing Check: Checks minimum longitudinal, shear and crack control reinforcement is provided as per ACI-318 Clause 11.7.
• Calculates moment-axial force interaction diagram for combined axial and bending analysis of the concrete shear wall.

The Australian concrete calculator for walls completes strength and detailing checks to the simplified method described in Chapter 11 of AS 3600-2018. Specifically it completes the following shear wall calculation checks:

• Shear Wall Stress Check: Calculates stress in shear wall to determine whether the wall is subject to compression across its entire section to comply with simplified design procedure as required by AS 3600 Clause 11.2.1.
• Compression Check: Checks the axial strength of the wall subjected to compressive force to AS 3600 Clause 11.5
• In-Plane Shear Check: Checks the in-plane shear strength of the wall subjected to lateral loads to AS 3600 Clause 11.6
• Detailing Check: Checks minimum longitudinal, shear and crack control reinforcement is provided as per AS 3600 Clause 11.7.

The design standard can be changed using the flag icon in the top of the left side input panel. The following design standards are currently supported:

• ACI 318 Shear Wall Design Software
• AS 3600-2018 Shear Wall Design Software

• ACI-318 concrete shear wall design

  Concrete shear wall design in ACI-318 is outlined in Chapter 11 of the design standard. A general outline of the process is detailed below:

  • Determine the relevant design actions for the shear wall subjected loads such as wind, seismic and gravity loads.
  • Use engineering judgement to create an initial estimate of wall geometry and reinforcement requirements.
  • Complete strength checks for all relevant design actions including axial, shear and flexural strength checks to ACI-318 Clause 11.5.
  • Complete reinforcement detailing checks to ACI-318 Clause 11.6 and 11.7
  • If necessary, revise wall geometry and/or reinforcement detailing to satisfy all strength and detailing requirements.

  The design of concrete shear walls can be an iterative process, with design sometimes needing to be revised as the design of a structure progresses. SkyCiv’s concrete wall calculator makes revisiting designs seamless by allowing users to generating a detailed calculation report for the concrete wall calculations.

  AS 3600-2018 shear wall design

  Concrete wall design in AS 3600-2018 is outlined in Section 11 of the design standard. A general outline of the concrete wall design process is detailed below:

  • Determine relevant design actions to be applied on the wall and evaluate the stress in the shear wall to evaluate whether it is subject to compression or tension.
  • Evaluate the applicable design procedures to be followed for the design of the shear wall. This is based on the following aspects:
    • Is the wall braced or unbraced.
    • Is the wall subject to in-plane loads and/or out-of-plane loads.
    • Is the wall subject to compression and/or tension across its section.
    • Height to thickness ratio and height to length limitations.
  • Complete strength checks to relevant design procedures. Depending on the design procedure to be adopted, the wall may be designed as a slab to AS 3600 Section 9, as a column to AS 3600 Section 10, or using the wall design directly to Section 11.
  • Complete reinforcement detailing checks to AS 3600 Clause 11.7.
