Efficient Lateral System:

Reduce No. Lateral Elements to 4

in each direction

Limit No. Irregularities Has a Predictable and Clean

Failure Mechanism

Does not interfere with the

Architecture & Assigned Use of Space

KEY ELELEMENTS KEY ELELEMENTS

Reduce Vase Shear:

Use a frame gravity system with a

higher R: 5.5

Reduce the Weight with a lighter Steel

Frame

Improved Capacity:

Higher f’c = 5ksi Thicker 24” walls Diagonally Reinforced Coupled Walls Higher T to increase participation of

coupled beam

Limit discontinuity and use symmetry to

keep a low ρ factor

CONCLUSION CONCLUSION

Current design reflects the labor

practices and situation of the country

Designers applied the best and most

economical design to a complicated structure

Coupled wall systems proved to be an

effective resisting system, allowed for increased floor area and architectural freedom

Reduced the amount of material and

labor required for the project

Overall: Good design when the

resources are available
