A study was conducted for the flexural retrofit of an old apartment house composed a reinforced concrete (RC) shear wall structure. For wall, vertical performed to both ends targeting slender improve performance. The materials were steel plate, epoxy, and non-shrink grout, they connected existing using post-installed chemical anchors. at broken retrofitted as much necessary maintain wall’s leng...

Infilled frame structures are commonly used in buildings. Masonry infilled RC frames are the most common type of structures used for multi-storeyed constructions in the developing countries, even in those which are located in seismically active regions also. Masonry infill walls are mainly used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. In the presen...

In the seismic design of structures, capacity design is typically employed to ensure that a desirable ductile response is obtained. In this paper three different capacity design approaches for reinforced concrete coupled walls are investigated. For a simple case study building, the expected capacity design shear forces and bending moments are calculated using the different approaches. The resul...

Currently, the upgrade of existing reinforced concrete (RC) buildings focuses only on energy retrofitting measures due to current policies promoted in scope European Green Deal. However, structural deficiencies are not eliminated, leaving building seriously unsafe despite investment, particularly seismic-prone regions. Moreover, envelopes RC responsible for their efficiency and seismic performa...

The work presented herein sets out to investigate numerically, by means of nonlinear finite element analysis, the effect of un-reinforced concrete or masonry infill walls on the overall structural response of reinforced concrete frames under static monotonic and seismic loading. For this purpose, a nonlinear finite element package purpose built for the analysis of concrete structures is employe...

The article presents a detailed comparison of two calculation models with Eurocode Standard guidelines. The stress has been put on defining the amount of reinforcement necessary to reduce the width of cracks resulting from imposed deformations in various ambient conditions. With the help of different approaches, the article presents the influence of the atmospheric factor on crack occurrence an...

The aim of this study was to evaluate the influence of thermal stress on the marginal integrity of restorative materials with different adhesive and thermal properties. Three hundred and sixty Class V cavities were prepared in buccal and lingual surfaces of 180 bovine incisors. Cervical and incisal walls were located in dentin and enamel, respectively. Specimens were restored with resin composi...

Reinforced concrete coupled walls are a common lateral load resisting system used in multi-storey buildings. The effect of the coupling beams can improve seismic performance, but at the same time adds complexity to the design procedure. A case study coupled wall building is designed using Force-Based Design (FBD) and Direct Displacement-Based Design (DDBD) and in the case of the latter a step b...

In this work, we analyze the influence of masonry infill walls on the seismic performance of waffle slabs reinforced concrete (RC) framed structures. We analyze buildings of three, five and eight storeys, which are representative for a big number of housings in Barcelona, Spain. Capacity spectra have been obtained by performing pushover analyses and we have used a simplified procedure to obtain...
