SEISMIC DESIGN CRITERIA&

DESIGN REQUIREMENTS FOR BUILDINGS

MYANAMR BUILDING CODE 2016

MYO ZIN AUNGShip Design Lab.Naval Architecture & Ocean Engineering

MYANMAR Building Code 2016 is based on:

• Minimum Design Loads for Buildings and Other Structures 7-05 (ASCE7-05)• Modify to be suitable with Myanmar’s land,

environment, available resources, natural disasters such as:• Flooding• Landslide• Cyclone• Earthquake, etc.

Criteria for the Design and Construction of Buildings Subject to Earthquake

• Earthquake loads are based upon Post-Elastic Energy Dissipation in the Structure• Because of this fact, the requirements for design, detailing,

and construction shall be satisfied even for structures and members for which load combinations that do not contain earthquake loads indicate larger demands than combinations that include earthquake loads.

Seismic Site Classes• Classes A, B, C, D, E, F• Based on – • Spectral Response

Accelerations• Site soil properties (Solid

Shear Wave Velocity in Top 100 ft.)• Important Factor

(Occupancy Category)

Maximum Considered Earthquake Ground Motion for 1 Sec Spectral Response Acceleration at 2% Probability in 50 Years with 5% Critical Damping, Site Class B

Sagaing fault

Maximum Considered Earthquake Ground Motion for 0.2 Sec Spectral Response Acceleration at 2% Probability in 50 Years with 5% Critical Damping, Site Class B

Seismic Zoning Map of Myanmar for Alternative Seismic Design Procedure

For Seismic Class C through F

• “Geotechnical Investigation Report” to be submitted• An evaluation of the following potential

geologic and seismic hazards: • Slope instability; • Liquefaction; • Differential settlement; • Surface displacement due to faulting or

lateral spreading, etc.

Criteria for the followings

• Member design, connection design, and deformation limit• Continuous load path and

interconnection• Connection to supports• Foundation design• Material design and detailing

requirements• Stress limit in the moment frames• Diaphragm Flexibility, Configuration

Irregularities, and Redundancy, etc.
