Plate Buckling and Steel Bridge Construction

Lecturer (assistant) 0000004490 3 SWS Sommersemester 2020 German See TUMonline See TUMonline

Objectives

After participating in the module, the students understand the normative verification methods of plate buckling (design of thin girders) and their theoretical backgrounds. The students are able to manage one project using inputs from the previous steel construction courses. This project is the design and calculation of one steel footbridge.

Description

Plate buckling: Scientific inference of buckling behaviour of plate-shaped components susceptible to plate buckling. Explanation of the normative verification. Steel bridge construction: construction forms and applications, orthotrope road plates, bridge bearing and lane transitions. Fatigue: Fundamentals of fatigue of metallic materials and the normative processing of the evidence against fatigue in the current standards. Ropes: Production and use of wire rope in the construction industry. Calculation of stresses and deformations of simple rope structures. Special issues for the detection of cable structures.

Prerequisites

Solve differential equations, visit the metal construction modules (basic course, supplementary course and design with metal) and static modules (basic and supplementary course)

Teaching and learning methods

The module consists of a lecture with integrated exercises. It is supported by Powerpoint presentation and supplemented by blackboard and further notes. Exemplary calculations will be carried out together in the lecture. Students will be included in the lecture and their understanding of the most important facts will be examined. Within the lecture, the material is deepened in an exercise. In this exercise, the lecturer and the students work together to fill in a void text. The lecturer will prepare the practice examples on site, whereby active participation of the students in the development of the solutions is very welcome. In order to promote independence and practice practical work, students design and calculate a steel pedestrian bridge in the form of a preliminary static, where they are supported by student tutors.

Examination

Description of achievement and assessment methods: The performance proof takes the form of a 75 minute exam, which is divided into part A general questions and part B computing tasks. Part A, which takes 15 minutes, aids are not allowed (close book). The student demonstrates in this part, that the basic interrelationships in plate buckling and steel bridge construction were understood. In part B, which is 60 minutes long, aids are approved (open book). By doing exercises (plate buckling, fatigue, cable) the students prove that they understand the verification formats according to Eurocode. In a study consisting of design, construction and calculation of one steel footbridge, the students additionally prove that they are able to apply the learning outcomes of the previous courses of steel construction in a larger static System. 10% of the study work and 90% of the exam arrives in the grading.
