For more information on built-up wood floor beams or wood ceiling beams (also called girders) see the Girder section of Rough Framing in Woodworking Online. This table is simply a sample and may not be valid for your region. In general, if you are staying within the limits of your beam span tables and floor joist span tables, you will not need to have beam calculations done by a structural engineer. View Size Selection Tables. A laminated beam span table, also called a span table or beam capacity table, is a chart that lists the load capacity of laminated wooden beams.

Structural engineers use span tables to choose wooden beams that comply with local building codes. What if we needed to span more than that?

For more precise lengths you will need to consult span tables. Or see our Design Your Own House tutorial site map. 1. �\�Qz�e��9T�����0���K`Y�������������G��i�x��7�)re�9p��?���}���o�^B�뢼.���&v�Ȧ��݇>+¢����]:�������a���J8\"�Ɓ/�H��D�q��o7��?^�T0j�Ʀɴ�H 0000006085 00000 n 0000006668 00000 n
