Problem 3 A column supports a roof and a second floor. The loads that act on the column are shown below. Using the ASCE 7 load combinations determine the factored design load in the column just above the second floor and the factored design load in the column just above the foundation. Show all load combination calculations and identify the controlling load combination and resulting load values at each design location. ( “ - “ load : indicates it is going away from the diaphragm surface)

Service Loads:

Roof Live Load 5.5 kip

Snow Load 6 kip

Roof Vertical Wind Load - 2.5 kip

Roof Horizontal Wind Load 9.2 kip

Roof Vertical Earthquake Load ±1.5 kip

Roof Horizontal Earthquake Load 9 kip

Roof Dead Load Maximum 3.5 kip

Roof Dead Load Minimum 2.75 kip

Live Load 9 kip

2 nd Floor Vertical Earthquake Load ±3.5 kip

2 nd Floor Horizontal Earthquake Load 20 kip

2 nd Floor Horizontal Wind Load 8 kip

2 nd Floor Dead Load Maximum 7 kip

2 nd Floor Dead Load Minimum 7 kip

The terrace roof of a building at sea level is planned to have a rectangular floor area with dimensions of 10 m and 20 m. The prevailing wind speed in winter is u∞=25 km/h, and air temperature is assumed to be T∞=0°C. Considering that the outer surface temperature of the building is To=10°C, how should the building be positioned with respect to the prevailing wind direction to minimize the heat loss from the roof?
