摘要

木-混凝土组合梁属于现代建筑。它们是通过连接木材和混凝土元素而创建的。它们的设计方式是，梁的混凝土部分放置在压缩区，木材部分放置在受拉区。不同类型的紧固件可用于连接，从机械(螺钉，钉子，穿孔板，钢型材零件等)到化学(各种类型的胶水)。在这项工作中，通过外部预应力对这种类型的梁进行主动加强的可能性进行了检查。显示了施加外部预应力的一种方法。通过试验试验确定了预应力梁和无预应力梁的试验结果。给出了所得结果并进行了比较。

Application of external prestressing to timber-concrete composite beams

Timber-concrete composite beams are classified as modern constructions. They are created by connecting a timber and concrete element. They are designed in such a way that the concrete part of the beam is placed in the compressed zone, and the timber part is placed in the tension zone. Different types of fasteners can be used for connecting, from mechanical (screws, nails, perforated plates, parts of steel profiles, etc.) to chemical (various types of glues). In this work, the possibility of active strengthening for this type of beam by external prestressing, is examined. One way for applying an external prestressing force is shown. By experimental testing are determined results for prestressed and beam without prestressing. Obtained results are presented and compared.
