TEEBEAM STRENGTH INGAL Longspan TeeBeams have been developed to suit new building designs that incorporate extended and uninterrupted openings in double brickwork, such as those required for large windows, and garage doors. INGAL Longspan TeeBeams make modern building designs possible by supporting brickwork above double-garage openings where a large single door is installed in preference to using two smaller doors separated by a brick centre support column.
act as a structural member and do not require the composite action of the masonry to support designated loads. When using Longspan TeeBeams there is no need to apply mortar between the brickwork and the TeeBeam to form a composite member. Similarly, location of expansion joints in masonry does not have an effect on the performance of the member. Simply select a suitable Longspan TeeBeam from the charts provided and lay the brickwork directly over the TeeBeam.
INGAL Longspan TeeBeams follow the tradition and proven ability of INGAL’S shorter TeeBeam range. Like the shorter TeeBeam section, Longspan TeeBeams have been designed to
In short, the superior strength and design of INGAL Longspan TeeBeams means they can ‘go the distance’ while also minimising work for builders.
FEATURES 1. Designed as a structural member, there is no need to create a composite member on site. 2. Cost savings compared to many specifically fabricated beans. 3. Hot-dip galvanized to Australian/New Zealand Standard AS/NZS 4680:1999 and in accordance with AS/NZS 2699.3:2002 (Built-in components for masonry construction). Durability rating of R3. 4. Optimum strength-to-weight ratio ensures ease of handling without compromising structural integrity. 5. Building code approved. INGAL Longspan TeeBeams satisfy the appropriate requirements for the following codes: • Material -250 Grade to the relevant Australian Standards. • Hot-dip galvanizing code - AS/NZS 4680:1999 • Masonry structures code - AS 3700:2002 • Built-in components tor masonry construction code - ASINZS 2699.3:2002 • Loads -AS 1170.1:1989+A1 and AS 1170.2:1989+A1+A2+A3. • The Longspan TeeBeam section has been optimised under the design rules of AS 4100:1998.
LOADING CATEGORIES There are two guide tables provided for structural arrangements often encountered in domestic and light commercial construction. To help select the appropriate Ingal TeeBeam for the application follow five easy steps: 1. Identity the type of construction i.e. Rafters/Trusses at right angles to TeeBeam - ‘Structural Arrangement A’ or Rafters/Trusses parallel to TeeBeam - ‘Structural Arrangement B.’ 2. Ascertain ‘Doorway Opening Span.’ 3. Ascertain ‘Rafter/Truss Span’ (for ‘Structural Arrangement A’) or ascertain ‘Batten Span’ (for ‘Structural Arrangement B’). 4. Determine the maximum ‘Height of Brickwork Above Opening in Courses’ over TeeBeam (at centre line of the opening). 5. Determine from chart if the TeeBeam is suitable for the applied loading (pink - suitable, red - not suitable). It is recommended that selection be made in consultation with a professional building adviser
INSTALLATION REQUIREMENTS 1. Ingal TeeBeams require an end bearing of 150mm for each end. Therefore, the maximum ‘Doorway Opening Span’ must not exceed the appropriate TeeBeam stock length, less 300mm. Note: Where the brickwork does comply with the ‘Brickwork Code’ the bearing capacity should be checked by a Structural Engineer. 2. Brickwork should be built up evenly on each side of the TeeBeam to avoid uneven loading, which may lead to distortion of the member and brickwork. 3. Brickwork is to be constructed in accordance with AS 3700 and recognised good industry practice.
LOADING CAPACITIES When a TeeBeam supports masonry over an opening, the load may be shared by three load carrying mechanisms acting either alone or in conjunction with the others, viz: 1. By the TeeBeam acting as a structural member alone. 2. By composite action between the TeeBeam and masonry acting together, much as reinforced concrete acts. 3. By arching of the masonry. It should be noted however, that due to the potential variability of the magnitude of composite action (i.e. from full capacity to near zero) the design of Ingal TeeBeams excludes any allowance for loads being carried by this mechanism. Similarly, the extent of aching action depends on the depth of brickwork and to a less extent on the degree of end restraint and for small numbers of courses the arching effect is minimal. Accordingly, the load charts for Ingal TeeBeams are based solely on the TeeBeam acting as a structural member, without composite or arching action.
LOADING RESTRICTIONS The loads associated with ‘Structural Arrangement A’ and ‘Structural Arrangement B’ are those typical of domestic and light commercial buildings and do not include any allowances for loads from items such as: 1. 2. 3. 4. 5. 6.
Hot water service. Solar heating. Roof space storage. Multi-storey construction. The load from any saddle truss or girder truss. Loads arising from non-standard roof framing.
