R.C structures have a certain age after which they are not safe to use. They deteriorate over time and become unsuitable for the purpose they were built for. R.C structures could be in the form of beams, columns, footings, ...
Civil infrastructures all over the world are prone to natural disasters causing colossal damages. These natural disasters range from falling weight, avalanches and accidental loads to earthquakes, floods and tornadoes. In ...
Fiber reinforced concrete is a concrete mix which utilizes fibrous material as reinforcement. These randomly oriented, uniformly distributed fibers exhibit a variety of properties when mixed with concrete. Steel fibers, ...
This research work reports the results of self-compacting paste (SCP) systems using SRMs like ASTM class F fly ash and powdered silica fume as 10% by mass replacement of cement. The role of hemi-hydrate and anhydrite in ...
Recently, sustainable development and environmental awareness have become important attributes of societal growth. An important role in this direction is attained through the sustainable development of built environment, ...
Analysis of structures subjected to extreme static and dynamic loads (such as earthquake, impact, wind and snow) using finite-element software are common and extensively being used in construction industry. However, to ...
Researchers have a concern that normal beam design procedures are not fully applicable to RC wide beams. Many studies have been conducted on RC wide beams and researchers have diverse results regarding shear strength of ...
This experimental study was devised to ascertain the effects of longitudinal reinforcement on shear strength of RC slender beams under uniformly distributed load instead of concentrated two point loading which has so far ...
The devastation in the recent events in Muzaffarabad Kashmir (2005) and Awaran Balochistan (2013) earthquake highlights the need for earthquake risk assessment (ERA). It is also suitable to develop the ERA framework in a ...
This study discusses the role of Limestone powder (LSP, Lafrage), Ground Granulated Blast Furnace Slag (GGBFS, Lafrage) and Silica Fume (SF 920, Elkem) on fresh and hardened properties / behavior of Self compacting paste ...
The influence of masonry infills on seismic response of reinforced concrete frame structures is one of the major fields of investigation for civil engineers in last few decades. Literature from proceedings of years of ...
Self-compacting concrete does not require manual compaction and is capable to flow under its own weight. Self-compacting concrete has found diverse applications in modern engineering practices including placements in heavily ...
The threats and damages of Earthquakes are intense and Pakistan is located in one of the most seismically active zones of the world. Historic earthquakes like Taxila earthquake of 25 AD, Quetta earthquake of 1935, Kashmir ...
The w/c ratio-strength relation plays a key role in selection of an adequate recipe against a particular target strength of concrete with and without admixtures. The relation proposed by American Concrete Institute (ACI) ...
In engineering practice, there are many situations in which structures undergoes impact or dynamic loading such as during an explosion, impact of ice load on pile structures, snow avalanches, accidental falling loads, ...
Pakistan is located in one of the seismically active zones of the world. Historic earthquakes like Taxila earthquake of 25 AD, Quetta earthquake of 1935 and Kashmir earthquake of 2005 bear testimony to the seismicity of ...
Natural disasters are events that cause immense damage and sufferings which happen unexpectedly. To mitigate the damage to infrastructures due to natural disasters such as avalanches, falling rocks, earthquakes and Blasts; ...
Self Compacting Cementitious Systems (SCCS) fall in the domain of modern concrete technology which has been used successfully through out the world. The major applications of such systems involve massive placements with ...
Moderate to high levels of seismic hazard are present through out the Pakistan and numerous collapsed by Oct. 8, 2005 Earthquake verified the seismic vulnerability of building type present in the country. Seismic retrofitting ...
