Structural Analysis
结构分析是土木工程专业的核心专业课，研究杆件结构在外界荷载作用下的内力、变形与稳定性的计算方法。内容涵盖静定与超静定结构的内力分析、位移计算、力法与位移法、矩阵位移法、影响线及结构动力分析基础等。课程注重培养学生建立计算简图、选择合适方法进行结构分析的能力，为后续钢结构和混凝土结构设计打下基础。
Structural Analysis is a core course for civil engineering, focusing on internal forces, deformation, and stability of framed structures under external loads. Topics include analysis of statically determinate and indeterminate structures, displacement computation, the force method, the displacement method, matrix stiffness method, influence lines, and fundamentals of structural dynamics. The course builds skills in modeling structures and selecting appropriate methods for engineering analysis.
学生需对一榀三层三跨钢框架进行结构分析，给定梁柱截面尺寸及竖向与水平风荷载。要求分别采用力法、位移法及矩阵位移法求解杆端弯矩与轴力，绘制弯矩图、剪力图与轴力图，并利用结构分析软件进行验算。最后结合计算结果对框架薄弱部位进行讨论，提出构件截面调整建议。
Students analyze a three-story, three-bay steel frame under specified vertical loads and wind loads. Using the force method, displacement method, and matrix stiffness method, member-end moments and axial forces are computed and corresponding diagrams produced. Results are verified with structural analysis software. Weak regions of the frame are discussed and section adjustments recommended based on the analysis.
