    How about a more realistic test? The building is almost empty. In this case the live loads would make up a larger percentage of the total load as compared to a concrete or masonry building. Design live loads are usually around 200 kg per square meter (40psf), but this building is mostly empty. Add watertanks and HVAC on the roof, bathtubs, furniture in every room, kitchens and tiles on floors and you end up with a much heavier building.
    Design earthquake loads for the Philippines, Japan or California should be much higher than 6.x. We experienced earthquakes above 7 and engineering should be tested up to 8+ magnitude earthquakes, which gives you a sideways acceleration of up to 1G.

    What is a "cold form steal building"? Is that similar to a frame used for houses except that it has steal studs instead of wood studs and not a steal structural frame used for high rises?

      light weight steel structures like used in steel purlins and sheeting rails. they are just thin steel sheets rolled in shapes like c-section, channels, z-purlins etc.

    I did not see at any moment in the building people or anything that simulates the weight of the live loads, which represent a more aggressive seismic behavior, due to the increase of mass by live loads...

      Live loads have a small influence in seismic combinations and also compared with self weight and permanent losds

    What about 4 storey : wide 20m x 60m length x 2m height side each storey, without columns or walls in middle

    We manufacture S275 double galvanized steel frames in our facility and ship them internationally. We've noticed a significant increase in demand for steel frames as many architects and custom home builders adopt this technology to gain a competitive edge, especially in hot, humid climates prone to natural disasters like earthquakes and hurricanes.

      Exactly, this seems like Mercalli scale instead of Richter scale.

    Funny they only show rhe back of the chinese people doing the test
    I get the feeling blacks weren't one of the people doing the test
