Fixed Tier Structures

Specialists In Seating can custom design, manufacture and install fixed tiered floors to suit any room size.
Fixed Tier Structures

Modular construction allows for ease of installation on site. This feature, when complemented with our in-house carpeting and seating installation, allows a classroom to be converted into a tiered lecture theatre, within a matter of a few days.

Converting a space into a tiered lecture theatre improves the overall room appearance, increases capacity and improves sight lines and overall learning experience for students. Fixed tiered structures can be manufactured to any riser and tread dimensions and can be constructed in a straight or curved configuration.

The structural design of the tiered floors conforms to the following regulatory and structural requirements:

BS 6399: Part 1; 1996 “Loading for Buildings”
BS 449: “The use of structural steel in building”

Design Criteria

Vertical deck loading: Satisfies the requirements of 4.0KN/m² uniformly distributed load, live loading as stated in BS6399. Loading capacity 5.0KN/m² in the aisle positions.
Horizontal loading: Satisfies the requirement of 0.6KN/m² uniformly distributed load [15% of the vertical loading] as stated in BS6399.

Construction

40 x 40 x 3.2 mm RHS section fully welded into supporting frames complete with baseplates 125 x 125 x 6.0 mm.
Supporting frames spaced at a maximum of 1200mm centres and linked laterally below deck level with 2N° sections of 40 x 40 x 4 mm RHS. Support frames provided with diagonal bracing as required by structural calculations.

Decking

All treads and risers finished with 25mm thick plywood securely fixed to supporting framework with TEK screws applied in accordance with the manufacturer’s instructions.
