The post-earthquake repair process of buildings is one of the key components of building seismic resilience. Understanding the details of the repair process in advance will benefit the evaluation and decision making for the seismic resilience of buildings. To this end, a five-dimensional (5D) simulation method on the post-earthquake repair process of buildings is proposed based on building information modeling (BIM), by which the repair activities can be presented in the way associated with a 3D model, time (denoted as the fourth dimension), and the related costs (denoted as the fifth dimension). First, a decision-making model of repair schemes based on the interval index of the possibility degree is created to determine the optimal post-earthquake repair schemes for a damaged building. Subsequently, an algorithm based on separate flow-repetitive process is designed to automatically make the repair schedule on a BIM platform according to the determined repair schemes. Finally, an algorithm of automatic mapping between the components in BIM and their repair schedules is developed, so that a 5D simulation of a post-earthquake repair process can be implemented. A six-story office building is selected as a case study, and the details of the post-earthquake repair process (e.g., the costs of labor, material and equipment over the repair time) are presented by the proposed 5D simulation method. The outcome of this study can be used to evaluate the seismic resilience of buildings and also to facilitate the decision making for seismically resilient buildings by providing the detailed guidance of the repair process.

基于BIM的建筑物震后修复过程的5D仿真方法

建筑物的震后修复过程是建筑物抗震能力的关键组成部分之一。提前了解维修过程的细节将有助于评估和决策建筑物的抗震能力。为此，提出了一种基于建筑物信息模型（BIM）的建筑物震后修复过程的五维（5D）仿真方法，通过该方法可以与3D模型相关联地呈现修复活动，时间（表示为第四维度）以及相关费用（表示为第五维度）。首先，基于可能性度的区间指标，建立了维修方案的决策模型，以确定受损房屋的最佳地震后维修方案。后来，设计了一种基于单独的重复流程的算法，根据确定的修复方案在BIM平台上自动制定修复计划。最后，开发了一种在BIM中的组件及其维修计划之间自动映射的算法，从而可以实现地震后维修过程的5D仿真。选择一个六层楼的办公楼作为案例研究，并通过提出的5D模拟方法介绍了震后修复过程的详细信息（例如，整个修复期间的人工，材料和设备成本）。这项研究的结果可用于评估建筑物的抗震能力，并通过提供详细的修复过程指导来促进抗震建筑物的决策。
