| Abstract: |
This article describes a modular timber/concrete composite system for short‐span highway bridges. The system is assembled from modules. Each module spans from support to support and consists of two glulam girders and a deck slab constructed of ultra high‐performance fiber reinforced concrete (UHPFRC). A method of analysis is proposed for the system to study both the longitudinal and transverse behavior under live loads. The method is based on a spatial grid model, which incorporates Vierendeel frames to account for partial composite action in the longitudinal direction. Preliminary results show that the proposed modular timber/concrete composite system achieves a high degree (91.4%) of longitudinal composite action and possess good transverse load sharing performance between modules. |
