Concrete Masonry (CMU) Wall Opening


Purpose and description

Tool to create an opening in the walls created by the CMU Wallplate that represents a structure such as a wall or roof panel

In Tekla Structures, a panel is created by picking two or more points.

In cast-in-place concrete the term wall refers to a concept similar to panel.

plugincomponent that is developed using Tekla Open API

Plugin is a .dll file and loaded inside Tekla Structures process.

Plugins can be started from the applications and components catalog.

System requirements

Environments: US Imperial, US Metric for other environments you may need to create or export/import cmu profiles and/or shapes.
Languages: English

Installing CMU Wall Opening

To install the extension:

  1. Download the CMU Tools TSEP package from Tekla Warehouse
  2. Import the TSEP into the Applications and components catalogcatalog that contains all system components and custom components, and the macros and applications

    (see TUA article for instructions)
  3. Start Tekla Structures
  4. Open/create a model
  5. The tool will be found in the CMU Tools sub-category of the US Extensions category of the Applications and components cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    .

Using CMU Wall Opening

After applying appropriate settings, select a wall created by the CMU Wall tool and then select a point in the wall for the opening location.

CMU Wall Opening settings

Opening

  1. Positioning options
    • Picked point is offset horizontally and vertically
    • Picked point is at lower left of opening
    • Picked point is at bottom center of opening
    • Picked point is at lower right of opening
  2. Positioning dimensions
    1. Total opening width
    2. Location point horizontal offset
    3. Total opening height
    4. Arc start height (set equal to Total opening height if no arc is desired)
    5. Location point vertical offset
    6. Arc curve height


Lintel

  1. Creation option:
    • None
    • Full
    • Individual
  2. Horizontal offset toward start of wall
  3. Horizontal offset toward end of wall
  4. Lintel block properties
  5. Block custom tagging
    • CMU Cut Lengthbolt property that indicates the depth at which Tekla Structures searches for the sections of the bolted parts

      Cut length determines whether the bolt will go through one flange or two, for example.

      Tag
    • CMU Height Tag
    • CMU Width Tag
    • CMU Length Tag
    • CMU Has Rebar Tag
    • CMU Decorative Color Tag
    • CMU Is Lintel Tag


Horizontal reinforcement

  1. Reinforcement properties for above and below the opening
  2. Vertical offset from block base above the opening
  3. Horizontal offset above the opening toward start of wall
  4. Horizontal offset above the opening toward end of wall
  5. Hook configuration and positioning above the opening
    • No hooks
    • Hooks at both ends pointed up
    • Hooks at both ends pointed up
  6. Vertical offset from block base below the opening
  7. Horizontal offset below the opening toward start of wall
  8. Horizontal offset below the opening toward end of wall
  9. Hook configuration and positioning below the opening
    • No hooks
    • Hooks at both ends pointed up
    • Hooks at both ends pointed up


Tie reinforcement

  1. Reinforcement properties for above the opening
  2. Number of spaces
  3. Center to center spacing
  4. Horizontal offset toward start of wall
  5. Horizontal offset toward end of wall
  6. Tie length at back face of wall
  7. Vertical offset from block base
  8. Horizontal offset from back face of wall
  9. Tie length at front face of wall
  10. Horizontal offset from front face of wall


Additional information

  • Picked point is projected to center planeplane whose position is defined so that it passes through the midpoint of a part cross section

    of wall which then needs to fall within the boundary of the wall parts.
