What kinds of loads can a structural member experience and what can that create?
Axial
eccentric
transverse
torsional
creates
tension and shear forces resulting in stresses
What are the 3 kinds of loads?
Dead- permenently in place items or structures
live- occupancy objects that can be moved
snow and wind
seismic- eg earthquakes
FYI- master stream delivers 4700 l/min and that translates to a load of up to 4700 kg/min added to a structure
what is the typical safety factor for a building?
2:1
What are collumns and what are the 3 types?
A column is a structural member that transmits axial compression loads
1 piers or compression blocks
2 short or intermediate
3 long or slender
What is a beam? 3 types?
structural member that carries loads acting in a direction which is transverse to the longitudinal axis of the member
1 simple supported at both ends
2 continuious supported in 3 or more locations
3 cantilevers rigidly supported at one end and project over a support point on the other
What is a truss?
framed structural member that utilizes a triangle or group of triangles in a plane to carry transverse loads.
What are the kinds of trusses (9)?
Bowstring
flat
gambrel
inverted king
inverted queen
kingpost
mono
cuttoff
room in the attic
what are the three types of building materials?
Non-combustible
combustible
fire resistant
what is considered a high rise building?
over 36 meters
or over 18 meters with a high occupancy to egress formula ratio
two types concrete + steel
What are low rise?
low rise and industrial are general terms that cover buildings that are up to aprox 6 stories difference from high rise is reduced code req. for fire resistance.
what are the 3 types of roofs?
flat, pitched and arched
the 6 types of pitched roofs?
hip, mansard, lantern, shed, gambrel, gable
What is the spotting zone when parking apparatus by an involved structure?
Allow for a collapse zone of 1.5 times the height of the building
