Numerical Study on Strengthening of Weak One-Way Slabs with HSC Laminates Subjected to Blast Load

High-performance reinforcement concrete due to its ductility and higher energy absorption has many applications in the field of passive defence than the normal concrete. These high-performance materials can be used in many cases, such as seismic improvement of building members. In some cases the str...
