WebThe effective width of the concrete slab is the sum of the effective widths for each side of the beam centerline, which shall not exceed: (1) one-eighth of the beam span, center to center of supports 45 ft.()2 8 = 11.3 ft. (2) one-half the distance to center-line of the adjacent beam 10 ft. ()2 2 = 10.0 ft. Controls WebJun 27, 2024 · However, in some cases, it may not be possible to satisfy all specification requirements while keeping the girder size to a minimum and keeping the strands near the bottom of the beam. This is more pronounced when debonded strands are used due to the limitation on the percentage of debonded strands. WebNov 8, 2024 · The section modulus is a cross-sectional geometric property of structural elements such as beams, columns, slabs, etc. and it is used to calculate stresses in Cross-sections. In general, it can be said that the greater the dimensions of a cross-section under a given load, the greater the Section modulus and the smaller the bending stress. homes in toms river new jersey
