Engineered Cementitious Composites for Enhanced Seismic Resistance of Interior Beam-column Connections

Engineered cementitious composite (ECC) is an ultra ductile cement-based material reinforced with fibers. It is characterized by high tensile ductility and tight crack width control. Thanks to the excellent performance, ECC is emerging in broad applications to enhance the loading capacity and the durability of structures. However, ECC also faces a limitation on dimensional stability

Effects of Temperature and Strain Rate on the Behavior of Strain-Hardening Cement-based Composites (SHCC) subjected to Tensile Loading

This paper reports the experimental findings on the tensile behaviour of strain-hardening cement-based composites (SHCC) subjected to elevated temperatures and different strain rates and to combinations of these parameters. Uniaxial tension tests with in-situ temperature control were performed at 22 °C, 60 °C, 100 °C and 150 °C. In addition, the effect of loading rate

Description of Near-tip Fracture Processes in Strain Hardening Cementitious Composites Using Image-based Analysis and the Compact Tension Test

The cracking mechanisms assume a key role in the composite behavior of Strain Hardening Cementitious Composites (SHCCs). Due to their importance, in previous studies the mechanical behavior of SHCC materials, as well as of other strain softening fiber reinforced cementitious composites, was characterized under eccentric tensile loading using the Compact Tension Test (CTT). The present

Characterization of the Interface between Strain Hardening Cementitious Repair Layers and Concrete Subgrade

Results of experimental investigations into the mechanical behavior of the interface between strain hardening cement-based composites (SHCC) and concrete are presented. Wedge splitting tests served for the determination of the mode I fracture properties of the interface. The corresponding stress-crack opening curves were determined by inverse analysis of the experiments. Expectedly, they strongly depend on

Uniaxial Tension Test Method using SHCC Prisms molded into Dumbbell Shape

Uniaxial tensile properties of a SHCC can be confirmed by simply fabricating prism specimens at the job site and molding those later into a dumbbell shape for uniaxial tension testing. Level of skill in fabricating dumbbell-shaped specimens and the use of vibratory consolidation led to no significant difference in the uniaxial tension test results. The

The Effect of Self-Healing on the Durability Performance of Micro-Cracked ECC

Increase in repair and replacement costs and poor performance of so-called conventional concrete materials force engineering society to pay serious attention to the durability issues. Many researchers agree on the general idea that cracking is vitally important if durability is of concern. Cracking of concrete under service conditions is inevitable due to several external factors

Simulating Crack Width Distributions in SHCC under Tensile Loading

A three-dimensional lattice model is used to evaluate the fracture behavior of Strain- Hardening Cementitious Composites (SHCC) in tension. Individual fibers are explicitly represented within the random lattice representation of the cement-based matrix. Comparisons are made with experimental measurements of crack openings and their evolution during increasing levels of tensile strain. The preliminary results indicate

Seismic behaviors of ECC/concrete composite beam-column joints under reversed cyclic loading

Engineered cementitious composites (ECC) are a class of high-performance fiber reinforced cement composite with strain hardening and multiple cracking properties. In this paper, a number of RC/ECC composite beam-column joints have been tested under reversed cyclic loading to study the effect of substitution of concrete with ECC in the joint zone on the seismic behaviors
