［摘要］鋼筋桁架模板近年來較多應(yīng)用于工程實踐中，用以解決施工上的困難，對鋼筋桁架混凝土組合樓板在正常使用階段的短期剛度進行了研究。以正交分析法進行了試驗，根據(jù)試驗數(shù)據(jù)，采用有效慣性矩法推導(dǎo)出了短期剛度的計算公式，計算出的理論撓度值與試驗實測值較為吻合，可以為這類鋼筋桁架混凝土組合樓板的設(shè)計提供參考。

Abstract:The rebar truss framework is nowadays widely used in the engineering practice to solve the construction difficulities. The short-term stiffness of concrete composite slabs with rebar truss at service ability limit state was studied. The tests were conducted based on the orthogonal analysis method, the calculation formulas of the short-term stiffness were derived using the effective moment of inertia method based on the test data, the calculated deflections agreed well with the test results. Therefore, the proposed design rules could provide references for the design of concrete composite slabs with rebar truss.
Keywords:rebar truss; composite slab; short-term stiffness
