CTCI Civil Structural Engineer interview questions

I applied for the engineer of RD group of Civil and Building division position. This position major in providing software maintenance and developing for structural engineers in CTCI. So the interview covered a structural exam(part 1) and software background exam(part 2) before the panel interview. You should finish both part 1 and part 2 in 70 mins. Part 1 included about 10 structural questions, covered Material Mechanism, Structural Mechanism, Reinforced Concrete Structures, and Steel Structures, but most of them are easy. Part 2 questions are listed below.
