Abstract

In low-to-medium-rise RC frame buildings, to sustain gravity and lateral loads, mostly, two main load-bearing systems are used; moment-resisting (sway) and moment-resisting with shear walls. In the UK, the use of shear walls has now become an expansive technique in these types of RC frame building, as indicated by The Concrete Centre. Furthermore, considering the structural behaviour and performance of shear walls in low-to-medium-rise RC frame buildings, in the areas with low risk of seismic load they may negatively affect the economic and environmental efficiency of the construction without any substantial improvement to the structural performance of the building. In this study, several steps will be undertaken to enhance the sustainability of construction in RC frame buildings, including the possibility of removing shear walls in low-to-medium-rise buildings which can directly influence the consumption of aggregates (as natural resources) and cement in concrete and speed up the construction process. Reducing the amount of concrete in the construction of RC frames may be a feasible option that would have a significant effect on the reduction of CO2. emissions from the construction industry. The results indicate that, considering the practical side of the design, it is advisable to design the buildings up to 12 storeys using moment-resisting frame with flat slab. The results, also, shows 12% reduction of consumed concrete and 4.6% of CO2. emission in moment-resisting frames compared to the frame with shear walls.
According to the outcome of this research and in collaboration with the Concrete Centre a design guide is developed for the use and implementation of moment-resisting frames in the UK construction industry.
