图40上比较了角钢结构和管结构的纵弯杆件的承载量,此数值取决于纵弯长度S_k[厘米];在自重g[公斤/米]相同的条件下进行比较。图40中,曲线a代表φ108/3.75毫米钢管,自重g=9.64公斤/米。图40 自重相同的角钢结构和管结构纵弯杆件承载量[t]的比较(取决于纵弯长度S_K[厘米])曲线b代表由两种边长不等之角钢合成的受压杆件((?) 55×75×5),自重g=9.9公斤/米。曲线c代表断面由两等边角钢构成的杆件,自重也为9.9公斤/米。图40上,管结构杆件的承载量[t]以100%表示,而由角钢组成的杆件的承载量(曲线b与c)均以占管结构承载量之百分率表示。
Figure 40 compares the load-carrying capacity of the angle-bend members of the angle structure and the pipe structure, depending on the longitudinal bending length S_k [cm]; under the same weight g [kg / m]. In Fig. 40, the curve a represents φ108 / 3.75mm steel pipe, and the self-weight g = 9.64kg / m. Fig. 40 Comparison of the load-carrying capacity of angle-bend members of angle-steel structure and pipe structure with the same self-weight (depending on the longitudinal bending length S_K [cm]) Curve b represents the pressure-receiving member composed of two angles of steel ((?) 55 × 75 × 5), weight g = 9.9 kg / m. Curve c represents the cross-section of the rod composed of two equal angles, weight is also 9.9 kg / m. In Fig. 40, the bearing capacity [t] of the pipe structure member is expressed as 100%, while the bearing capacity of the member composed of the angle steel (curves b and c) is expressed as a percentage of the load capacity of the pipe structure.
