| Concrete-filled fiber-reinforced plasterboard(CFFRP)structure is a promising structural system. Its developments and applications are the need of reformation of wall material of china. In order to replace masonry structure and realize the introductions and applications of this structure in china, CFFRP structure is studied preliminarily. Lintel builded with concrete-filled fiber-reinforced plasterboard is an important part of CFFRP structure, so studying the appearance of the lintels has an important theoretical significance and engineering value.Fiber-reinforced plasterboard affects carrying capacity of lintels builded with concrete-filled fiber-reinforced plasterboard, which should be taken into account. Based on the experiment studies of 9 lintels builded with concrete-filled fiber-reinforced plasterboard under uniform load, this paper not only discusses the elements that affect initial strength, bending capacity and shear strength. But also gives out calculated formulas that can calculate the load for initial strength, bending capacity and shear strength.Contrasting our and Austrilian experimental values with calculated formula of the paper, the results indicated that this formula suggested by this paper could estimate the load properly.By using general finite element modeling software-ANSYS, the lintels are made nonlinear finite-element analysis. The calculated results are much coincided with the tested results, which proved the feasibility of software-ANSYS to calculate structure of concrete-filled fiber-reinforced plasterboard. By using ANSYS, the other elements that affect the shear strength of concrete-filled fiber-reinforced plasterboard are also discussed. |
