Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

Smart fiber reinforced concretes (FRC) are good in intelligent environmental response. With the smart FRC being used buildings such as bridges and tunnels, real-time online distributed monitoring of concrete state can be realized. It provides an excellent solution to reduce emergencies caused by accumulation damages, resistance attenuation, etc. This paper analyzes FRC’s self-sensing self-heali...

Lightweight concrete (LWC) is a kind of concrete that made of lightweight aggregates or gas bubbles. These aggregates could be natural or artificial, and expanded polystyrene (EPS) lightweight concrete is the most interesting lightweight concrete and has good mechanical properties. Bulk density of this kind of concrete is between 300-2000 kg/m3. In this paper flexural strength of EPS is modeled...
