项目摘要

This study investigated an analytical procedure of seismic risk estimation for reinforced concrete structures and applicability of risk finance as alternative risk transfer. Then numerical simulations of the risk assessment for three types of RC piers were carried out.1. Seismic risk analysis was conducted in order to quantitatively evaluate damage and loss of reinforced concrete structures under various levels of seismic actions.Part 1 : Structural performance of RC piers Evaluation was first of all calculated by the conventional ways.Part 2 : Seismic hazard curves and multi-events curves at a construction site are examinedPart 3 : Assessment of vulnerability and damage for RC piers by means of newly proposed EFM-method were conducted.Part 4 : Finally analytical procedure of seismic risk assessment were established. Then, wizard type software FrameRisk was constructed.2. Risk FinancePart 1 : Development Methodology of Discounted Seismic Risk Curve.The present value of reduction principal and interest depend on the time when earthquake hits. We proposed an evaluation method of discounted present value of a seismic risk curve in a contract period of investment.Part 2 : A Study of Financial Impact Analysis and Management Accounting for Alternative Risk TransferThe long-term financial strategy based on the financial impact analysis and the management accounting technique is needed to design ART. We investigated the financial impact analysis, and developed the prototype model of management accounting.

本研究研究了钢筋混凝土结构地震风险评估的分析程序以及风险融资作为替代风险转移的适用性。然后对三种类型的钢筋混凝土桥墩的风险评估进行了数值模拟。 1．进行地震风险分析是为了定量评估钢筋混凝土结构在不同级别地震作用下的损坏和损失。第1部分：RC桥墩的结构性能评估首先采用常规方法进行计算。第2部分：地震危险曲线和检查施工现场的多事件曲线第 3 部分：通过新提出的 EFM 方法对 RC 桥墩的脆弱性和损坏进行评估。第 4 部分：最终的地震风险分析程序建立了评估。然后构建了向导式软件FrameRisk。 2．风险金融第一部分：地震风险折现曲线的开发方法。折现本金和利息的现值取决于地震发生的时间。我们提出了投资合同期内地震风险曲线贴现现值的评估方法。第二部分：替代风险转移的财务影响分析和管理会计研究基于财务影响分析和风险转移的长期财务战略设计ART需要管理会计技术。我们调查了财务影响分析，并开发了管理会计的原型模型。
