Joints in frame structures often fail before beams and columns in an earthquake and are a key part of reinforcement. In this study, to enhance the seismic performance of concrete frame structures, a steel-jacketed grouting composite reinforcement method is proposed by combining reinforcement technology, steel cladding technology, and eco-efficient materials …

Khalid et al. investigated the performance of plastic wastes in fibre-reinforced concrete beams [20, 31]. In their research, ring-shaped PET (Figure 5) was loaded into the concrete in order to improve its fracture energy, compressive strength, beam flexural strength, and splitting tensile. It also illustrated that the plastic fibres added to ...

Concrete is the most widely employed material in building construction and has a crucial role in providing health and a safe environment to the global population, being after water the most used resource (Henry and Kato, 2014).In fact, if properly produced, concrete has exceptional durability and mechanical characteristics, and is an excellent engineered material …
