Conceptual design of major structures is highlighted with the aim of achieving multi-hazard mitigation.Two interdependent levels of structural safety(i.e.reliability,robustness) are defined and their relationship examined.It is argued herein that multi-hazard mitigation can be conducted through structural robustness analysis.Moreover,given the applicability of energy(flow) principles,multi-hazard mitigation based conceptual design will be implemented by improving the energy-absorption capacity of structures while reducing the potential release of external energy.Finally,the paper proposes active and passive means of mitigating multi-hazard from the viewpoints of building space,materials,structural system,and construction,which should prove useful in reducing the risk of disproportionate failure under disaster condition.
