Structural Failures due to in adequate structural detailing
- Failures due to Non-compliance with Code Minimum Requirements
- Failures due to Building Configurations Problems
- Failures due to poor Architectural Detailing
- Failures due to poor Interaction of Non-structural Components
- Failures due to poor Ductility
- Failures due to Pounding
- Failures due to poor Foundation Support
- Failures due to Landslide
- Failures due to Tsunami
refers to architectural design of building details such as columns or walls that may affect the structural detailing in ways that are detrimental to good seismic design practice
Failures due to poor architectural detailing
ability of the structure to sustain large deformation but it will not collapse
