The Network for Earthquake Engineering Simulation has found a means to make six-storey wood-frame buildings - which are now permitted in British Columbia - more earthquake resistant. But that method, which was tested last month, will add to the construction costs for such buildings.
In an email, Colorado State University civil engineering associate professor John van de Lindt, who led the test, said his team is working with an engineer in California to figure out the exact price tag. But, he wrote, "Off the top of my head I would anticipate about 5 percent to as much as 8 percent (more) for some areas."
The British Columbia government, which was a partner in that test, hasn't yet said whether it will make that method mandatory.
