Abstract : This paper presents a new concept for a lightweight GFRP slab. The slab construction consists of two layers: a glass fiber-reinforced (GFRP) sections and lightweight concrete (LC). Mechanical tests on six slabs were performed with three parameters the spacing between the GFRP sections, The geometry of GFRP cross section and the stiffeners. Increasing the spacing between GFRP sections reduced the ultimate load capacity of the slab by Increasing the spacing from 233 to 350 lead to reduce the ultim

Abstract : Egypt is now at risk of drought, and Cairo will be hurt. It is the sixth-most vulnerable city to environmental risks and the least resilient among 50 global cities. The government hasn't explored the impact of drought on the urban sector as it has on the agricultural one.
