A Design a pin-connected southern pine square column (S4S), using the NDS provisions. The column is to support an axial compressive load of P kips. The unbraced length is L ft. Refer to Blackboard for values of P and L. Enter the random variables generated by Blackboard here: Load (P) Unbraced Length (L) Ibs ft Enter reference values here: Modulus of Elasticity of timber species Allowable compressive stress of timber species (F) Effective length factor (K) psi psi $7 38 2.) 39 30 1 2 3 4 15 16 17 18 19 50 $1 52 53 54 55 56 $7 58 59 БО 51 52 53 14 55 16 in Enter calculated values here: Effective length (KL) in inches Slenderness (KL/d) Alpha variable (a) Stability Adjustment Factor (C) Allowable stress of column (F) Allowable load of column Pacal) psi Ibs Enter the properties of your chosen timber here: Nominal size of chosen timber Area of chosen timber (A) Least dimension (d) in in
