Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

Question

Problem:
A continuous girder system as shown in Grid 3 is consists of G11, G12 and G13
girders. The slab resting on these girders have the following superimposed dead
loads:
Metal Deck with Reinforced
Concrete Slab:
Floor Finish Type:
Ceilings (Below the Slab):
Frame Partitions:
Miscellaneous (MEPF):
3.5 kPa
Hardwood Flooring, 22mm
Gypsum board, 10mm
Movable Partitions
0.24 kPa
Girders (G11, G12 &G13) carry a uniform superimposed dead load of 8.1 kN/m
due to the perimeter wall.
The slab carries a live load of Residential Basic Floor Area.
In the initial analysis, beams (B5, B10, B15, B17 & B19) were assumed to be
W6x20. Girders (G11, G12 &G13) were assumed to be W16x50.
Earthquake analysis from a software was conducted and the reactions at the
exterior supports (joints A & D) are as follows:
At joint A:
Shear force (VA) = 62 KN
Moment (MA) = 105 kN-m
At joint D:
Shear force (VD)
Moment (MA)
= -58 KN
= -95 kN-m
1. Determine the controlling load combination for LRFD and the
corresponding factored load (Shear and Moment) in the exterior supports.
2. If the resistance factor is 0.90, what is the required nominal strength?
3. Determine the controlling load combination for ASD and the
corresponding required service load strength (Shear and Moment) in the
exterior supports.
4. If the safety factor is 1.67, what is the required nominal strength based on
the service load strength?
