The aim of this study is to compare the seismic performances strengthening techniques applied reinforced concrete (RC) non-ductile frames tested under effects loads. In experimental part study, one-third scale, one-bay, two-storey hollow brick infilled RC were strengthened with five different and reversed cyclic lateral One being reference, bricks plastered on both sides, one was plain mortar, ...

Abstract Precast slab parameters are important factors affecting the mechanical performance and service life of precast-slab-fabricated recyclable roads. To clarify force mechanism roads provide a basis for selecting parameters, field test road fabricated using large-scale precast was conducted in this study. The horizontal vertical stresses on top bottom surfaces determined. stress-time histor...

Around New Zealand there has been an increasing trend of ‘hybrid’ multi-storey buildings that combine reinforced concrete walls with structural steel framing systems. This study aims to characterise and understand this type building, focusing on constructed in Auckland Christchurch from 2014 onwards. Drawings a total 50 were reviewed, their features documented, including building use, height, l...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

Polyamide 6 intercalated/exfoliated (PIE) cements are fabricated and characterized. With the reinforcing nanointerphase, the flexure strength of a PIE cement is higher than that of ordinary cements by an order of magnitude. The optimum nanointerphase content is around 10 wt.%. This technique has great potential in developing advanced precast and repair technologies. © 2005 Elsevier B.V. All rig...
