چکیده
This article describes design concept and material characteristics of a new ductile fiber reinforced cementitious composite referred to as ECC (Engineered Cementitious Composite). This particular ECC contains Polyvinyl Alcohol fiber and exhibits remarkably ductile tensile property with over 1% of tensile strain capacity. The high tensile strain performance of the ECC was found successfully utilized to improve the performance of structural elements via two demonstrative examples. First, it was found that ECC significantly enhanced shear performance of short span beam under cyclic loading. Second, ECC enables one to realize simple dry joint connecting panels with remarkably high shear load capacity for structural wall assembly. As conclusion, a strong potential of the ECC has been established to enhance the structural performance of seismic resistant elements.

Buckling of bridging fibres in composites
In brittle materials such as concrete and ceramics, fibre reinforcement has been widely accepted as an effective way of improving their strength and toughness. In addition, a notable pseudo strain-hardening phenomenon can contribute to a significantly enhanced ductility of the composite when an adequately designed fibre system is used. This condition was first proposed by Aveston et al. [1], an...
متن کاملDesign of green engineered cementitious composites for pavement overlay applications
The construction, repair and rehabilitation of concrete pavements relies on the production and flow of large quantities of concrete and its constituents. Within the US, nearly 43 megatons of cement are used annually for the construction, repair and rehabilitation of concrete pavements, accounting for over 39 megatons of CO2 emissions. To reduce environmental impact and improve the sustainabilit...

Proteins of the FtsZ (filamentous temperature sensitive Z) family establish complex polymeric spatial patterns in plastids of the moss Physcomitrella patens. These structures represent a “plastoskeleton” that might contribute to plastid shape and stability. Because additional forces, such as electrostatic interactions, are effective between molecules and atoms at the nano-scale, the applicabili...
متن کاملReinforced Ecc - an Evolution from Materials to Structures
While significant advances have been made in concrete materials and in concrete structures over the last decade, research in materials and in structural engineering are often carried out separately. As a result, opportunities in major leaps in structural performance may be missed, or research emphasis in materials development may be misguided. This paper introduces the concept of integrated str...
متن کاملSubstructure Model for Concrete Behavior Simulation under Cyclic Multiaxial Loading
This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
