For live loads not exceeding 100 psf (4.79 kN/m2), the design live load for any structural member sup- porting 150 square feet (13.94 m2) or more is per- mitted to be reduced in accordance with Equation 16-24. For one-way slabs, the area, A, for use in Equation 16 …

ARCH 331 Note Set 22.1 Su2014abn 5 Reinforced Concrete Beam Members Strength Design for Beams Sstrength design method is similar to LRFD. There is a nominal strength that is reduced by a factor which must exceed the factored design stress.
ARCH 331 Note Set 28.1 Su2014abn 2 Reinforced Masonry Design Structural design standards for reinforced masonry are established by the Masonry Standards Joint Committee consisting of ACI, ASCE and The Masonry Society (TMS), and presents allowable stress design as well as limit state (strength) design.
Connections Connections must be able to transfer any axial force, shear, or moment from member to member or from beam to column. Steel construction accomplishes this with bolt and welds. Wood construction uses nails, bolts, shear plates, and split-ring connectors. Single Shear - forces cause only one shear “drop” across the bolt.

Pure Bending in Beams With bending moments along the axis of the member only, a beam is said to be in pure bending. Normal stresses due to bending can be found for homogeneous materials having a plane of symmetry in the y axis that follow Hooke’s law. Maximum Moment and Stress Distribution

These values assume that the safe superimposed load is composed of 60% dead load and 40% live load. In some cases, loads in excess of those shown can be accommodated by modifying the general parameters such as concrete strength and/or reinforcing patterns.
