我国土木工程创新研究及其演化分析

Analysis of research of civil engineering innovation and its evolution in China

以土木工程领域三本高水平核心期刊2000年以来近2万篇文献为数据来源,采用文献计量方法,对关键词进行相关统计和可视化分析,宏观辨识土木工程创新研究热点和演化趋势,微观探析抗震性能研究的演化特征。研究表明:有限元分析是最常用的方法,抗震性能是最受关注的研究热点,研究主题之间具有交叉融合的特征;抗震性能研究从传统框架结构扩展至高层建筑抗震、结构体系抗震及新型抗震结构等,数字化设计、模拟仿真和智能监测等新技术已成为新趋势。

Taking nearly 20,000 documents from three high-level core journals in the field of civil engineering since 2000 as the data source,the bibliometric method is used to carry out relevant statistics and visualization analysis of keywords,macroscopically identify the hotspots of innovative research and evolution trends in civil engineering,and microscopically analyze the evolution characteristics of seismic performance research.The study shows that:finite element analysis is the most commonly used method,seismic performance is the most popular research hotspot,and there is cross-fertilization between the research topics;seismic performance research is expanded from traditional frame structures to high-rise building seismic,structural system seismic and new seismic structures,etc..Digital design,analog simulation and intelligent monitoring have become new trends.
