Steel

Front 1

Alloying

Back 1

Adding other elements such as chromium, copper and nickle

Front 2

Simple beam moment:

Back 2

Positive

Front 3

Cantelivered beam moment

Back 3

Negative moment

Front 4

Ibc deflection limit

Back 4

The deflection limit for steel members is L/360 for live load only.

Front 5

Rule of thumb for depth of beam

Back 5

1/22 of the span

Front 6

Composite beam

Back 6

Steel beam and concrete slab connected to resist bending stresses

Front 7

Shear stress in a beam

Back 7

The unit shear stress fv is equal to V/dt. The shear stress should be checked for beams with a short span and a heavy load. The shear stress should be checked for beams with a large concentrated load near the support.

Front 8

Smaller axial load =

Back 8

Larger slenderness ratio

Front 9

Moment of beam

Back 9

Pounds * (span)^2 /8

Front 10

Less deflection in beams with

Back 10

Greater moment of inertia

Front 11

The most common type of reinforcing steel used for flexural members in buildings

Back 11

ASTM A615 Grade 60. (60,000 psi)

Front 12

Min covering for rebar

Back 12

3" when exposed to earth

3/4 - 1 1/2 " on inside applications

Front 13

Ties spacing

Back 13

The ties must be at least #3 in size, and the spacing of the ties may not exceed 16 times the diameter of the longitudinal bars or 48 times the diameter of the tie bars

Front 14

Reinforcing in columns

Back 14

At least 6 bars in spiral columns

Min 0.01- .08max area of cross section.

If spacing between bars are more than 6in then second tie is needed

Front 15

Slenderness in reinforced concrete columns

Back 15

Can be ignored

Front 16

Splice overlap

Back 16

Not less than 40x the diameter of bar

Front 17

Reinforced concrete problem

Back 17
