[提要]  經(jīng)簡(jiǎn)化分析建立了鋼塑輕質(zhì)板正截面抗彎承載力計(jì)算公式，并提出了板的改制方法。試驗(yàn)表明，改制板的承載能力和變形能力均有較大提高，且理論計(jì)算與實(shí)測(cè)承載力吻合較好；未改制的鋼塑板呈少筋脆性破壞特征。無(wú)論改制與否這種板僅能單向傳力。
[關(guān)鍵詞]  鋼塑輕質(zhì)板 抗彎承載力  實(shí)驗(yàn)分析

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 one-way bearing capacity.
Keywords: steel-plastic lightweight  slabs; flexural strength; experimental  analysis
