Statics
静力学是土木工程专业的基础力学课程，主要研究物体在力系作用下的平衡规律。内容包括力的合成与分解、力矩与力偶、受力分析、平面与空间力系的平衡条件、桁架内力分析、摩擦以及形心与惯性矩计算等。通过本课程的学习，学生将掌握对工程结构进行受力分析的基本方法，为后续学习材料力学、结构力学等课程奠定坚实基础。
Statics is a fundamental mechanics course for civil engineering, focusing on the equilibrium of bodies under force systems. Topics include force composition and resolution, moments and couples, free-body diagrams, equilibrium of planar and spatial force systems, truss analysis, friction, and centroids and moments of inertia. Students develop essential skills in analyzing forces on engineering structures, providing a solid foundation for advanced courses in mechanics of materials and structural analysis.
学生需选择一座简支桁架桥梁，绘制结构简图并完成完整的受力分析。要求采用节点法和截面法计算各杆件内力，绘制轴力图，并校核关键杆件的平衡条件。最终提交一份包含计算过程、受力图与结论的分析报告，并附手算与软件验算的对比结果。
Students select a simply supported truss bridge, draw the structural diagram, and perform a complete force analysis. Using the method of joints and method of sections, member forces are calculated, axial force diagrams produced, and equilibrium of key members verified. A final report including calculations, free-body diagrams, and comparison between hand calculations and software verification is submitted.
