Lateral Loads
 Wind load
North/South Direction Base Shear 1.6(419)= 670 kips
East/West Direction Base Shear 1.6(305)= 488 kips
• Seismic load
Base Shear 838 kips
• Governing lateral load
V seismic = 838 kips > V wind = 670 kips
Lateral Loads
 ASCE 7-05
For wind loads: Section 6.5: method 2
For seismic loads: Chapters 11 - 12
Equivalent Lateral Force Procedure

ETABS computer modeling
 Lateral system was modeled and designed
 Diaphragms were assumed to be rigid
 All seismic forces were applied at the center of mass
 Braces were assumed to be pinned at both ends
 Lateral beams were assumed to be fixed at both ends
 Modeling of all beam and column elements took loading
deformations into account
 Seismic drift was determined based on ASCE7-05
