October 28th Observations from Van
As a not very atypical example, his building at beginning appear to have only non-structural damage. But it came out that there is a heavy stair damage with a loss of about 50% of the section. Such type of damages with no clear sign from outside, but with seriously impaired members inside creates a difficult situation for street type […]

Performance of a strengthened School Building
Original shear walls of the structure along the north-south direction has honeycomb shear cracks in the first three stories with decreasing intensity. Cracks at the base are about a mm wide. Added shear walls for strengthening along the north-south direction show signs of separations at the upper beam and column interfaces for the lower two […]
Main Problem: Fundamentally Flawed Structural Designs
The area has seen a boom in building construction in the last decade, and it is obvious that they had pushed beyond the limits of conventional practice into the realm of improperly engineered and structurally flawed designs. The mistakes are fundamental and obvious. The typical mistakes are soft story, torsion, inadequate lateral strength. Captive column mistake also exists, but at much lesser […]
