Primary Framing

Primary Framing

Primary frames are designed in accordance with the steel construction manual published by American Institute of Steel Construction (AISC). Manufacturing dimensional tolerances are in accordance with the requirements of 'Metal Building Manufacturers Association (MBMA) of USA, "Low Rise Building Systems Manual". Besides AISC and MBMA, we also design buildings with IS-875, 1984 and IS-875, 2007. Built-up sections are fabricated from hot rolled steel plates confirming to ASTM A 572M grade or equivalent with a minimum yield strength of345N/mm2 (50ksi).

The most common primary framing systems are illustrated here. All structures shown are symmetrical about the ridge line. Framing systems unsymmetrical about the ridge line and Multispan Framing Systems with unequal width modules are possible too. Practically any frame geometry can be erected.

Building without interior columns - maximum practical width = 90 m

Arched Clear-Span - maximum practical width = 90 m

Maximum practical width = 24 m

Maximum practical module width = 80 m

Building with one interior column - maximum practical module width = 70 m
More multi-spans are possible (AMS-2, AMS-3,...)

Building with one interior column - maximum practical module width = 70 m

Building with two interior columns - maximum practical module width = 70 m

Building with three interior columns - maximum practical module width = 70 m

Maximum practical width = 30 m

Building without interior columns - maximum practical width = 50 m
