The program of the present study involved fabrication, casting and studying the behavior of composite steel concrete beams exposed to impact loads. Two composite beams were performed so as to study the impact behavior produced by falling mass on these beams. Two types of concrete with different strength were included. Testing apparatus with differe...

Castellated steel profile sections can be used in order to increase the flexure strength of composite concrete-steel beams for building large spans. Castellated beams are fabricated by cutting I-section steel girders in a special manner before welding to produce an opening throughout the web. The depth of the new section is enhanced by a specific p...

In which fabrication of composite castellated steel self-compacting concrete beams which connected to self-compacting concrete by means of stud shear connectors. Four composite castellated beams were performed with different degre...

The architectural designer likely tends to provide more space for one or more storey inside the multi-storey building by means of many methods; one of them by using floating columns, which means the end of any vertical element rest on a beam that leads to discontinuity of columns in such type of multi-storey buildings. So it has been used shear wal...

Urbanization has led to the damage of infrastructure due to floods and water accumulation on roads and sidewalks. To address this problem, pervious concrete was designed to drain water smoothly. However, pervious concrete has certain drawbacks, such as brittleness and poor tensile strength. To overcome these shortcomings, it is reinforced with fibe...

Challenges posed by industrial solid waste, particularly Electrical Cable Waste (ECW), have been increasingly recognized due to their environmental implications and substantial decomposition timelines. ECW, a byproduct of aggressive demolition and reconstruction in Iraq, has seen limited investigation regarding its potential use as an aggregate sub...

Concrete is a brittle material, so it is reinforced with fibers (such as steel, glass and nylon fibers) to improve its ductility. On the other hand, the use of fibers resulting from waste is an interesting issue to avoid the negative impact of these wastes on the environment as well as converting them from useless to other valuable materials. Limit...

Abstract. This analytical study aims to investigate the flexural behavior of simply supported RC beams having longitudinal hole with circle cross section under monotonic two point loads. The commercial FE program ABAQUS was used for simulating and implementing the specimens behavior that tested experimentally in previous researches. The overall spe...

The present study involved assessing the replacement of fine aggregate in the mortar with sustainable local materials like clay bricks and glass included 168 specimens (cubes and prisms). Seven mixtures were cast for this work, one control mix (R1) with 100% natural sand whereas mixes from R2 to R5 have 10% and 20% replacing natural sand with waste...

The main objective of this study is to assess the effect of utilizing waste material (lightweight concrete blocks) as partial replacing of fine aggregate. To do so, seven mix designs were utilized to prepare 168 mortar specimens (84 cubes and 84 prism) with the replacement ratios of 10% and 20% waste material fine aggregate instead of traditional s...

The exposure of concrete or cement mortars to fire or other elevated temperatures negatively affects the mechanical properties, and a change may also occur in the pore structures, leading to cracking and spalling. In order to hinder or reduce the negative impact of elevated temperature on cement mortar, as well as to promote reuse of waste in the c...

In the current study, attention was focused on effects of using wastes of plastic and glass of juices and soft drink bottles in concrete, and the optimum percent's of the wastes were detected giving the best properties of concrete. The total number of concrete mixes was (12), which have different wastes additions details. These mixes included: thre...
