    Wind loads - servicaebility and ultimate

    Hi, I am new to this forum and I am new to Australian standards. For wind load calculations, I have seen serviceability and ultimate wind speed. I am wondering why there are two categories for wind. Where to use this serviceability wind loads? Thankyou
