A reduced-degree-of-freedom (RDOF) model for seismic analysis of predominantly plan-symmetric reinforced concrete (RC) wall–frame buildings is introduced. The RDOF the building consists elastic beam–column elements with concentrated plasticity used simulating cantilever walls and RC frame that are represented by improved fish-bone (IFB) model. In this paper, capability demonstrated two building...

In the last decades, need to develop new enhanced typologies of steel reinforcement bars with improved ductility and durability performance in presence aggressive environmental conditions progressively increased due negative consequences that corrosion showed on structural capacity reinforced concrete (RC) buildings. Within recently concluded NEWREBAR research project, a reinforcing grade Dual-...

The seismic safety of existing building stock has become a very critical issue in recent years, mainly earthquake-prone South Europe where most the buildings were designed before enforcement standards. Therefore, concept, development and testing efficient cost-effective retrofitting technologies are nowadays strongly needed, both for society scientific community. This study deals with assessmen...

The objective of this research is to quantitatively measure and compare the environmental load and construction cost of different structural frame types. Construction cost also accounts for the costs of CO₂ emissions of input materials. The choice of structural frame type is a major consideration in construction, as this element represents about 33% of total building construction costs. In this...

Earthquake loads can induce out-of-plane deformations in thin reinforced concrete (RC) walls that may lead to member out-of-plane failure or cause a premature in-plane collapse. Such instability phenomena have been observed after the recent earthquakes in Chile (2010) and New Zealand (2011). Walls with single layer of vertical reinforcement are more vulnerable to instability issues than the typ...

This paper describes the results of experimental testing of glass fiber reinforced plastic (GFRP) composite beam strengthened reinforced concrete (RC) slabs with two symmetrical openings. Specimens, one-half scale, have been designed and fabricated to reflect the most common RC bathroom slab used in school buildings. The specimen had dimensions of 2000 mm (width) × 150 mm (thickness) × 3000 mm ...
