“…The replacement of ulin wooden by floordeck in concrete work is planned both in the preparation and execution process so that the casting is completed faster, very efficient in terms of installation. Using a steel floordeck to replace ulin wooden bridge floor can save cement, formwork, and scaffolding by up to 25-30% in material usage (Clouston & Schreyer, 2008;Johnson, 2018). The construction design of the previous condition is shown in Figure 1, and design of the improvement innovation using a floordeck is as shown in Figure 2.…”

Infrastructure in the form of bridges is very important for Buntok Regency in Central Kalimantan where the area is swampy or lowland area. Total wood bridge construction is 45% from total 163 bridge in this area that most of them are not proper condition considering some wood materials need to be replaced. The innovation has been created to find the effective way how to maintenance the wooden bridge that has been idle for long time due to broken material on superstructure of the bridge. The floor of bridge that constructed with previous materials of ulin wooden bridge replaced by composite materials with floordeck concrete combination. The implementation of Tampa Bridge maintenance innovation showed better performance in terms of safety, comfortable and smoothness of bridge users from community around. In terms of budget aspect, the maintenance is cumulatively more efficient than if carrying out floor changes every year considering no longer possible to find ulin wood anymore. On technical point of view, with reinforced concrete can be applied to wooden bridges selectively only on ulin wooden bridges whose substructure is still intact and only minor damage to the spoorband and floor occurs. Bridge maintenance procedures need to be create to keep better maintenance for longer life time of the existing bridge that can be applied for another wooden bridge for maintenance.

“…Three EWP (LVL, LSL and CLT) and commercial ready-mix concrete were combined with different connectors (self-tapping screws (STS), (10mm diameter ASSY STS with Canadian approval (CCMC ( 2013), the proprietary glued-in steel connector Holz-Beton-Verbund (HBV) (Clouston and Schreyer 2008), and a combination of STS and adhesive bond using epoxy adhesive, see Table 1. Acoustic insulation is sometimes desired for enhanced performance of TCC floors; herein, Foamular® C-200 polystyrene rigid insulation with a compression strength of 140kPa was utilized.…”

There is much potential for engineered wood products to be used beyond low-rise residential construction when incorporating the notion of hybrid systems like timber-concrete-composites (TCC). TCC systems are comprised of a timber element connected to a concrete slab through a shear connection. By combining the complimentary properties of timber and concrete, the performance of timber floors can be enhanced, including bending stiffness, load-bearing capacity, dynamic response, airborne sound transmission, structural fire rating, and thermal mass. A large number of T-beam TCC systems existed for decades; however, the growing availability of panel-type products in North America offers designers greater versatility in terms of structural and building physics performance. While stiffness and strength design of TCC systems is straight-forward, there is little design guidance available in terms of vibration and long-term performance. The bending, vibration and long-term performance for a range of TCC systems in several EWPs were validated on small-scale shear tests, floor panels subjected to serviceability loads for 2.5 years, and subsequent full-size bending tests. The tests confirmed that calculations according to the ?-method can predict the basic stiffness and dynamic properties of TCC floors within a reasonable degree of accuracy.

“…The type of shear connection between the timber and concrete components greatly influences the structural properties of TCC floors. A wide range of connection systems are available, ranging from mechanical connectors such as bolts [12], lag screws [13], or selftapping screws (STS) [14], glued-in perforated steel plates [15], composite connectors [16], adhesive bonds [17], notched connections [18], or steel kerf plates [19].…”

FPInnovations, a not-for-profit research organisation for the Canadian forest sector and affiliated industries, developed a technical design guide for timber-concrete composite (TCC) floors meeting multi-design requirements. It provides the design criteria along with the calculation methods to control the elastic and long-term deflection, the vibration induced by human walking and the structural resistance, as well as guidance for the fire-resistance design and the behaviour of the shear connection. The technical guide has been used to develop design provisions that are expected to be implemented in the next 2024 edition of CSA O86. This paper presents a summary of this Canadian design method.
