ABSTRACT

The choice of economic reinforced concrete slab for residential spaces has constrained slab types to be rigid with closed supports and framed construction partitions that require demolitions before adjustment or absolutely inhibit a change of use. This restrains slab design to offer lesser clear spans as the most economical option for residential buildings. Most research have considered the use of Ribbed and Waffle slabs for commercial buildings, but this ignored the rising demand for the concept of space adaptability and flexibility of residential spaces. Residential buildings should offer spatial functionality that creates social symbiotic connections between the end-users and the building to avert the loss of value attributed to change of use, cumbersome renovation routines and displeasure of conformations. Structural engineers must integrate structural safety, integrity, stability, economy, aesthetics and user satisfaction, without compromising the ease of construction, sustainability and trending demands of innovation. Using synopses from previous studies, this paper reviewed the comparative analysis and design of conventional solid, ribbed and waffle slabs for a five-storey residential building with respect to an effective, economical, robust and worthwhile option for wide-range residential flexibility. A structural design with the open house concept of clearer-span of residential spaces will enhance sustainability design, produce lightweight structures, minimise cumbersome construction processes and offer multiple user-functionality and long-term satisfaction of residential buildings.
