课程概述

Structural mechanics is a major course for undergraduate students of civil and hydraulic engineering in structural analysis. As the basic theories, students should have learned engineering mechanics and mechanics of materials. Structural mechanics studies the relationships between the external loads applied to a deformable system and the intensity of internal forces acting within the system. The purpose of this course is to help students and engineers develop a fundamental understanding of the principle of framed structural analysis. An equally important purpose is to develop an understanding of the behavior of structural systems under loads.

There will be an emphasis on a number of key areas of study: 1) geometric stability of structures; 2) fundamentals of the analysis of statically determinate structures; 3) principle of virtual work and displacement of structures; 4) analysis of statically indeterminate structures.

This course consists of 64 hours, 4 periods per week and 16 weeks of study. The course integrates structural mechanics experiment, and creates a new teaching idea of combining experiment with theory, which will help students understand the concepts and principles well.
