The study on seismic risk evaluation and the risk finance for reinforced concrete piers

本文研究了钢筋混凝土结构地震风险评估的分析方法，以及风险金融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进行了风险评估的数值模拟。为了定量评价钢筋混凝土结构在不同程度地震作用下的损伤和损失，进行了地震风险分析。第一部分：钢筋混凝土桥墩结构性能评估，首先采用常规方法进行计算。第2部分：研究了建筑工地的地震危险曲线和多事件曲线。第3部分：采用新提出的efm方法对RC桥墩的易损性和损伤进行了评估。第四部分：最后建立了地震风险评估的分析程序。然后，构建向导型软件FrameRisk。风险金融学第一部分：地震风险折现曲线的开发方法。还本付息的现值取决于地震发生的时间。提出了一种投资合同期内地震风险曲线贴现现值的评价方法。第二部分：替代风险转移的财务影响分析与管理会计研究设计替代风险转移需要基于财务影响分析和管理会计技术的长期财务战略。我们研究了财务影响分析，并开发了管理会计的原型模型。

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.
