Wind analysis can include but is not limited to evaluating comfort, wind loading on structures, as well as pollution, and natural ventilation. Below, further explanation and real-life wind evaluations and wind simulations will be discussed.

Live load reduction factors are a function of the area associated with the loads acting on a member. In calculating the reduction for a given load, the program only uses the area on the member associated with that live load type.

Moment-resisting frame is a rectilinear assemblage of beams and columns, with the beams rigidly connected to the columns. Resistance to lateral forces is provided primarily by rigid frame action – that is, by the development of bending moment and shear force in the frame members and joints.

Interior walls and partitions that exceed 6 feet (1829 mm) in height, including their finish materials, shall have adequate strength and stiffness to resist the loads to which they are subjected but not less than a horizontal load of 5 psf (0.240 kN/m2).

A handrail is a rail that is designed to be grasped by the hand so as to provide stability or support. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls. Handrails are typically supported by balusters or attached to walls.

Diaphragms shall be considered flexible for the purposes of this paragraph when the maximum lateral deformation of the diaphragm is more than two times the average story drift of the associated story. … Strictly following this code definition would result in many light-frame diaphragms being classified as rigid
Flexible Diaphragm with an Opening Read More »
Diaphragms are classified as flexible or rigid depending on how they distribute loads to the frames/walls. Flexible diaphragms are not capable of distributing lateral forces in proportion to the rigidities of vertical elements. … Diaphragms constructed with wood or sheet metal are typically classified as flexible.

The most common example is a discontinuous shear wall or braced frame. The element is not continuous to the foundation but stops at an upper level. The shear at this level is transferred through the diaphragm to other resisting elements below.

All structural framing elements and their connections not required by design to be part of the lateral force-resisting system shall be designed and/or detailed to be adequate to maintain support of expected gravity loads when subjected to the expected deformations caused by seismic forces. Increased demand due to P Δ effects and story sidesway stability

The roof deck is the roofing material between the structural components (the trusses and joists) and the insulation and weatherproofing layers (roof materials, coatings, layers, etc.). … For residential buildings, the most common type of roof deck is plywood or tongue and groove wood systems.
