maximum of 20 percent, but the live load shall not be less than L as calculated in Section 1607.10.1. 1607.10.2 Alternative uniform live load reduction. As an alternative to Section 1607.10.1 and subject to the linn- tations of Table 1607.1, uniformly distributed live loads are permitted to be reduced in accordance with the follow- ing provisions.

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
