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...

The voided slab system has been known as an effective technique to replace a heavy reinforced concrete without the decrease in flexural strength. However, according previous studies, capacities such strength, stiffness and ductility of slabs were practically lower than that solid depending on void shapes details. Therefore, this study, analytical experimental study conducted derive optimal shap...

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that reinforced (RC) connection – CFT connections. The experimental program was carried out on five large-sized samples, including three UPC samples two RC samples. Steel plate details were utilised to increase bond betwee...

AIM The aim of the present study was to evaluate whether the use of simplified ethanol-wet bonding (EWB) technique improved the immediate microtensile bond strength (μTBS) between resin composite and caries-affected dentin (CAD). MATERIALS AND METHODS Twenty-four extracted carious human permanent molars were sectioned to expose the carious lesion. The carious dentin was excavated until CAD wa...

This paper uses computational simulation to investigate the lateral load-displacement behavior and failure modes of a modern 14-story reinforced concrete (RC) core wall building. The design complies with minimum code requirements current California Building Code, which is based on ASCE 7–16 ACI 318–14. representation building, accounts for material nonlinearities all structural components, empl...
