|
is a state of balance or zero motion
|
Equilibrium
|
|
|
is a simplified sketch of a structure or part of a structure solated from its supports which shows all active and reactive forces acting on the structure
|
Free Body Diagram
|
|
|
Are structural members that resist loads applied transverse to their longitudinal axis
|
Beams
|
|
|
two bracing systems that provide lateral stability for a pinned frame
|
Rigid Frame
and Shearwalls |
|
|
Roof and floors are horiontal planes that must be supported against lateral movement. these horizontal planes are called
|
Diaphragms
|
|
|
Lateral force-resisting walls are called
|
Shearwalls
|
|
|
Loads uniformly distrobuted over and area of a roof or floor are assigned to individual members based on the concept of
|
Transverse shear force
|
|
|
is the manner in which loads travel throughout thhe structure
|
load path
|
|
|
involves the sysematic prcess of determining loads and support reactions of individual structural members as they in turn affect the loading of other structural elements
|
load tracing
|
|
|
is a tranverse section in a beam span where the bending momnet is zero
|
point of inflection
|
|
|
the sagging of a beam subjected to loads that create bending
|
deflection
|
|
|
the equations of static equilibrium for a rigid body that lies on a plane (x,y)
|
Sum Fy = 0
Sum Fx = 0 Sum M = 0 |
|
|
the internal force system, which exists within a beam to resist the applied forces and moments, consists of
|
The bending Moment, Shear, and Normal Force
|
|
|
equation that indicates that at any section in the beam the slope of the moment diagram is equal to the shear.
|
dm/dx = V
