Who are you and what is your research topic?<\/h3>\n

My name is Anzhi Wang, I come from China and studied civil engineering at TU Braunschweig. I am now continuing my work at TU Braunschweig and doing research on material status assessment for existing steel structures at the Institute of Steel Structures.<\/p>\n

Which research question are you working on?<\/h3>\n

Many structures around the world, especially bridges, are under fatigue load. Fatigue causes the aging of structures to accelerate. When a structure is “too old”, it loses its designed functions. Therefore, the structure should be assessed. Material status, among other things, is important but difficult to assess. With the help of various digital optical measurement methods, we can perform non-destructive “mechanical tests” on structural components and determine the material status.<\/p>\n

What inspires you about your research?<\/h3>\n

I am especially excited about the possibility of developing an assessment method that could probably be used in the future. In addition, I am also excited about learning and trying different methods and techniques to solve the scientific problem during my research time.<\/p>\n

Why is your topic relevant to the Future City?<\/h3>\n

Digitization is very important for the future management of structures. Not only the geometry but also the material of a structure should be digitally documented. Non-destructive material status assessment can contribute a lot to the documentation of existing structures.<\/p>\n

What is special about participating in the Research Training Group \u201cModelling the constitutional evolution of building materials and structures with respect to aging\u201d?<\/h3>\n

The structural supervision of several professors and the regular exchange with colleagues who work on more or less similar topics, but with different methods or techniques.<\/p>\n","protected":false},"excerpt":{"rendered":"
