  Abstract:

  Apart from many advantages, High Strength Concrete (HSC) has disadvantages in terms of brittleness and poor resistance to fire. Various studies suggest that when polypropylene (PP) fibers are uniformly distributed within concrete, they play an active role in improving spalling resistance of concrete when exposed to elevated temperature while having no adverse effect on its...

  Abstract:

  In architecture, interlace structural concept is considered as a new design approach for cosmopolitan cities with high density to minimize the land use and increase the interaction. With various architectural approach, land resources can be minimized by this interlace concept for residential complexes. Such buildings will eliminate the reduction of land resource problem and on... More

  Abstract:

  Response modification factor is an essential factor in seismic analysis to provide economic design of reinforced concrete structures. Base shear force is divided by the response modification factor to consider the ability of the structure to dissipate energy through plastic hinges. The current study investigates the effects of changing some parameters on response modification factor... More

  Abstract:

  With the increased application of High Strength Concrete (HSC) in

  construction and lack of proper guidelines for structural design in India,

  behavioral study of high strength concrete is an important aspect of

  research. Research on the behavior of HSC reinforced beams with concrete

  strength more than 60 MPa has been carried out in the past and is still

  continuing to... More

  Abstract:

  Various modes of compacting the asphalt concrete mixture can create

  mechanically different behaviour of the prepared specimens and can alter

  its sustainability. An attempt has been made in the present assessment to

  prepare asphalt concrete specimens by implementation of three modes

  of compaction, the gyratory, the roller, and the Marshall hammer. The

  specimens were prepared at the target bulk density... More

  Abstract:

  The operation of reinforced concrete structures is directly associated with the adhesion between the steel bar and the concrete, which allows the internal forces to be transferred to the reinforcement during the process of loading the structural elements. The modification of the concrete composition, with the introduction of recycled aggregate from construction and demolition waste... More

  Abstract:

  The prediction of the behavior of reinforced concrete beams under bending is essential for the perfect design of these elements. Usually, the classical models do not incorporate the physical nonlinear behavior of concrete under tension and compression, which can underestimate the deformations in the structural element under short and long-term loads. In the present... More
