# 6.3.2 *T-Beam Geometry*

JUMP TO FULL CODE CHAPTER

For nonprestressed T-beams supporting monolithic or composite slabs, the effective flange width

**shall include the beam web width***b*_{f}**plus an effective overhanging flange width in accordance with Table 6.3.2.1, where***b*_{w}**is the slab thickness and***h***is the clear distance to the adjacent web.***s*_{w}**Table 6.3.2.1—Dimensional limits for effective overhanging flange width for T-beams**

Flange location | Effective overhanging flange width, beyond face of web | |
---|---|---|

Each side of web | Least of: | 8h |
