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...

A Comparative Analysis for Land Utilization：Steel and R/C Interlaced Structures
1-7
Article ID: 1940
1074 (Abstract) 45 (Download)
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...

Seismic Response Modification Factorof Reinforced Concrete Frames Basedon Pushover Analysis
30-38
Article ID: 818
724 (Abstract) 56 (Download)
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...

Failure Evaluation of Reinforced Concrete Beams Using Damage Mechanics and Classical Laminate Theory
1-9
Article ID: 5028
366 (Abstract) 49 (Download)
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...
