I think the shear walls at first level in east-west direction are not strong enough. Acturally most of new houses in london have this problem. I am looking for a new house recently. I told a builder my concerns about this problem two weeks ago before this tragity happened. People like open concept design, this make the back side wide open by adding big window and sliding door, also the front is wide open because the garage door and main entrace door. Inside the house there are no shear walls. Structurally, we don't consider drywalls as shear wall, though drywalls help to resist the wind load. Also some builders don't provide strong tie or braces due to the price issue. The Ontario Building Code is acturally not a high standard for housing design. If we use Part 4 (Standard for bigger house or building) almost all house designs fail. If someone is looking for a new house or thinking to buy a lot and build your dream house from scratch recently, we can share our experiences. my email: guolijun2001@yahoo.com. By the way the destroyed houses were built by Primium Homes. |
