The technical evaluation has not been finished yet though.
I personally don't know exactly the structure of those buildings that collapsed. But we have been told that the absence of ties within the salls and of proper connections to other structural elements most likely to be the reason for damage(s). This means it is not the material itself but the inadequate use of it by design or construction.
I'm referring to a concrete masonry internal skin tied to brick masonry external skin. This is the most popular construction type in the UK. I know that the majority of New Zealand homes are timber frame with cladding (often in brick as mentioned above) and I just wondered if building with two layers of masonry is possible under the code without being too uneconomic compared to timber frame. I assume the masonry structure being heavier and more rigid than timber would need adaptation to it's design for it to be as suitable for withstanding earthquakes and this could prove costly.
