Abstract

Abstract

Timber-concrete composite structure can significantly improve the structural performance of timber buildings and can be widely mostly used in multi-story and high-rise timber buildings. However, due to the lack of research on the vibration performance of timber-concrete composite floor systems, effective design bases are still not available at present. Steel bar truss slabs have been widely used in prefabricated concrete structures. In this regard, the dynamic properties of timber-concrete composite beams using steel bar truss slabs were explored experimentally. Through the push-out test, the anti-shear performance of shear connectors was obtained, and the flexural rigidity of the composite beams was calculated. Furthermore, through dynamic tests, the dynamic properties such as natural vibration frequency and damping ratio of the composite beams were obtained. In addition, according to theoretical calculation, the effects of connector types and steel bar truss slabs on the dynamic properties of the composite beams were analyzed, and the comfortability of the composite beams and the accuracy of calculation models were evaluated based on existing standards.
