Attention

Re7.13 Air conditioing unit in 4th floor pay atten tion to z/h = 3/4

Re7.18 Fp  I found correct631 and allowable is given 1050    I didn't 631*.7=483 then 1050/438=4.17'

Smaller Cs always govern!!?

For wood design always pay attention to factors most common 0.7 and 2.8

Non Building Vbase  Ch12 Or 15 Base on T<0.06  But Checks  just using ch15

Simplified design   Fa   page 119      1        1.1             1.2    problem 33-55 last series

Use adjusted length = (2b/h) × length for segments with AR > 2:1 when computing allowable unit shear   Ex. 14-55 last series 

Drag force is like a deflection diagram that is found from the area of net shear diagram

Site class D Default site class problem 3-55 last series 

Chapter 15  for calculating V pay attention to similar or non similar to building 

When you see allowable in a problem, keep in mind there might be a reduction parameter!

pay attention to the entire problem, for example, if say middle column along line b  series 2 35-55

Snow load less than 30psf ignore

One-story anchorage, pay attention to wall height

Equation Fp=....................(1+2* z/h)   understand  z and h very tricky
