To　efficiently　improve　the　security　of　buildings　against　extreme　accidents,　the　Architectural　Society　of　China　organized　a　special　committee　to　compile　the　Design　Specification　for　the　Collapse　Prevention　of　Buildings.　Based　on　the　corresponding　research　in　China　and　the　relative　design　codes　in　various　countries,　this　specification　recommends　design　and　analysis　methods　for　the　prevention　of　earthquake-induced　collapse,　progressive　collapse,　fire-induced　collapse,　construction　error-induced　collapse　and　so　on.　This　paper　provides　a　brief　summary　of　the　framework　of　this　specification　and　presents　the　main　innovative　work　in　it,　for　example:　the　improved　tie　force　method,　the　progressive　collapse　resistance　demand　based　on　energy　method,　the　earthquake-induced　collapse　resistance　evaluation　based　on　incremental　dynamic　analysis　and　the　fire-induced　collapse　prevention　design　calculations.　©　2014　American　Society　of　Civil　Engineers.
