Heads up: There are no amended sections in this chapter.
The structural system shall include (a) through (g), as applicable:
(a) Floor construction and roof construction, including one-way and two-way slabs
(b) Beams and joists
Structural systems shall be designed to accommodate anticipated volume change and differential settlement.
Every structure shall be assigned to a Seismic Design Category in accordance with the general building code or as determined by the authority having jurisdiction in areas without a legally adopted building code.
In structures assigned to Seismic Design Category B, C, D, E, or F, the effects of those structural members on the response of the system shall be considered and accommodated in the structural design.
In structures assigned to Seismic Design Category B, C, D, E, or F, the consequences of damage to those structural members shall be considered.
Effects of nonstructural members shall be accounted for as described in 220.127.116.11 and consequences of damage to nonstructural members shall be considered.
Diaphragms and their connections shall be designed to provide lateral support to vertical, horizontal, and inclined elements.
Collectors shall be provided where required to transmit forces between diaphragms and vertical elements.
Analytical procedures shall satisfy compatibility of deformations and equilibrium of forces.
Evaluation of performance at service load conditions shall consider reactions, moments, torsions, shears, and axial forces induced by prestressing, creep, shrinkage, temperature change, axial deformation, restraint of attached structural members, and foundation settlement.
The strength, serviceability, and durability requirements of this Code shall take precedence over sustainability considerations.
Structural members and their connections shall be in accordance with structural integrity requirements in Table 18.104.22.168.
|Nonprestressed two-way slabs||22.214.171.124|
|Prestressed two-way slabs||126.96.36.199|
|Nonprestressed two-way joist systems||188.8.131.52|
|Nonprestressed one-way joist system||184.108.40.206|
|Precast joints and connections||220.127.116.11|
Structural concrete members shall satisfy the fire protection requirements of the general building code.
Design, fabrication, and construction of precast members and their connections shall include the effects of tolerances.
Where system behavior requires in-plane loads to be transferred between the members of a precast floor or wall system, (a) and (b) shall be satisfied:
Distribution of forces that act perpendicular to the plane of precast members shall be established by analysis or test.
Design of prestressed members and systems shall be based on strength and on behavior at service conditions at all critical stages during the life of the structure from the time prestress is first applied.
Provisions shall be made for effects on adjoining construction of elastic and plastic deformations, deflections, changes in length, and rotations due to prestressing. Effects of temperature change, restraint of attached structural members, foundation settlement, creep, and shrinkage shall also be considered.
Stress concentrations due to prestressing shall be considered in design.
Individual members shall be designed for all critical stages of loading.
Reinforcement shall be detailed to minimize cracking and to prevent separation of individual components of composite members.
Composite compression members shall include all members reinforced longitudinally with structural steel shapes, pipe, or tubing with or without longitudinal bars.
