钢塑轻质板的正截面抗弯承载能力

Experimental Analysis on Steel - Plastic Lightweight Slabs Under Flexural Load

经简化分析建立了钢塑轻质板正截面抗弯承载力计算公式,并提出了板的改制方法.试验表明,改制板的承载能力和变形能力均有较大提高,且理论计算与实测承载力吻合较好;未改制的钢塑板呈少筋脆性破坏特征.无论改制与否这种板仅能单向传力.

Based on a simplifying analysis, the flexural strength of steel-plastic slabs was proposed, and an improved method for slab-manufacturing was suggested. The tests predicted that the improved slabs occupied better bearing capacity and larger failure strain, and the calculated resulted ones coincided with the tests better. The failure of unimproved slabs was brittle. Either improved or unimproved slabs had only oneway bearing capacity.
