The results show that RC beams strengthened by CFRP or GFRP can increase the shear bearing capacity of the beams, but has little effect on the beamstiffness.
结果表明，采用纤维对钢筋混凝土梁进行剪切加固后，其抗剪强度明显提高，但对梁的刚度和变形影响较小。

Finally, the existing beamstiffness analysis of calculation methods established for the new steel-concrete composite beamstiffness and deformation calculation.
最后通过对现有组合梁刚度计算方法的分析研究，建立了适合新型钢-混凝土组合梁的刚度和变形计算方法。

Students will determine the relative stiffness of two aluminum beam test specimens of equal cross sectional area but different cross-sectional shape and see how they conform to theory.
