检查和评估结构
RC结构的检验和评估是评估基础设施条件的最佳方法。检查被认为是任何结构维护计划的第一步。检查可以像结构的记录视觉条件一样简单，或者更复杂的形式，例如对事件或灾难的法医研究，以便了解劣化和降解的起源和性质。每当精确时......阅读更多 ”检查和评估结构

如何评估混凝土的抗压强度
What is the best method for the measurement of compressive strength of concrete? Testing cylinders and cubes in compression is the most convenient and well-known method for measuring the strength. The main question is if one can design and develop a method that can measure the strength faster, easier, and more accurate? Can all the advancements in sensor technology and better understanding of the development of concrete microstructure can help…阅读更多 ”如何评估混凝土的抗压强度
智能结构健康监测
I would like to start this by a very simple example: that infrastructure facilities work very similar our body. When they are first built (i.e. like when we are at our young age), they operate at their best. Just a routine checkup is all you need to keep up the good form. As they get older, more problems start to appear; and when are old (at the end of their…阅读更多 ”智能结构健康监测
Nondestructive Reliability Assessment of Structures
What is the most reliable and appropriate method for evaluating a structure? Well, that is the question we have been facing a lot lately. Clients ask for the affordable, yet precise methods to evaluate the safety and reliability of their capital intensive assets. In order to understand the situation, one needs to understand the economy of the structure under investigation, that is how far our inspection and evaluation methods can…阅读更多 ”Nondestructive Reliability Assessment of Structures
用于FRP安装质量控制的NDT方法
纤维增强复合材料(玻璃钢)materials are utilized to improve flexural strength, shear strength, and ductility of existing sub-standard structures. Concrete elements strengthened by FRP sheets at tension zone are good example. FPRs improve the tensile strength of concrete. Another great example is to improve the flexural capacity of columns through lateral confinement. Problematic of FRP Installation Despite the advances in frp material design and fabrication, the quality control and…阅读更多 ”用于FRP安装质量控制的NDT方法
5 NDT Methods for Structural Evaluation
NDT methods can be used in routine inspection projects; they can be used to follow up the state of damages in periodical checks. The other advantage of NDT methods is that they can be performed by minimum intervention to the structure. This helps prevent aggravating the problems in already damaged structure. NDT methods can be used to assess the condition of elements that do not have easy access. One example…阅读更多 ”5 NDT Methods for Structural Evaluation

Ontario Structure Inspection Manual
安大略省结构检验手册于1985年以来，安大略省结构检测手册已被用于安大略省的桥梁检查。本手册在2000年（OSIM，2008）年度进行了重大修改。此常见问题解答提供了OSIM 2008中使用的一般定义和术语。
Deterioration of Concrete Structures
Deterioration of reinforced concrete structures can happen for a number of reasons. Physical and Chemical processes can impact durability and structural performance of the concrete. Defects in design, materials, workmanship, curing and maintenance can all impact the service life, safety and reliability of an element. In this article, we will review some of the most common types of deterioration mechanisms in concrete. Share on linkedin Share on facebook Share on…阅读更多 ”Deterioration of Concrete Structures
How to Test Damaged Bridges?
Damaged Bridges are a major concern in the maintenance and operation of transportation infrastructure. Bridge structures in North America were mainly developed in the 1960’s and 1970’s and are rapidly approaching the end of their initial service life. Major mega cities in North America spend millions of dollars each year to keep these structures safe and functional. According to the ASCE 2013 report card, “one in nine of the US bridges are…阅读更多 ”How to Test Damaged Bridges?
