Wet Mix Shotcrete Used in Subsea Tunnel Environments
To reject the claim that the use of accelerator in shotcrete reduces the compressive strength with time, lately cored samples were taken from an 18 to 19 years old concrete. A wet mixed...
The Influence of Water Glass on the Technological Parameters of Shotcrete
Shotcrete used in tunneling must follow a clearly defined early strength development in order to comply with stresses from rock deformations and drilling and blasting. Accelerators are...
Shotcrete Tests at the Fish Ecca Tunnel
The Fish-Ecca Tunnel is situated in the Eastern Cape and forms part of the Lower Fish Irrigation Scheme. About 25% of the 5032 m tunnel had to be lined with shotcrete. Between February...
An Identity Chart for Steel Fibers
Improvements in ductility and toughness by adding steel fibers to the shotcrete mix are sufficient to enable steel fibers to be used as replacement for steel mesh reinforcements. Steel...
Steel Fiber Reinforced Shotcrete?For Rock Support and Fire Protection
Rapid development in concrete technology and development of equipment has led to a change from dry hand-operated to wet robot shotcreting in Norway. Shotcrete of more than 100 MPa cube...
ASTM C666 (A) Freeze-Thaw Durability of Air-Entrained Wet- and Dry-Mix Shotcrete
In order to assess the freeze-thaw durability of shotcrete, six samples of dry-mix shotcrete and one sample of wet-mix shotcrete were mixed outdoors at Hydro-Quebec's research institute...
CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...
Seismic Behavior of Weak-Column Strong-Beam Frames
An experimental evaluation of the seismic performance of moment-resisting steel frames using Weak-Column Strong-Beam joints is described. A simulated seismic response is imposed on five...
Seismic Behavior of High Strength Concrete Columns
Information on the ductility of high strength columns in seismic areas has been scarce. The available information is based mainly on small test columns subjected to monotonic concentric...
High-Strength Concrete Joints Under Cyclic Loading
This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American...
Orthotropic Rigidities of Curved Concrete Waffle Slabs
Analytical expressions are derived for predicting the flexural and torsional rigidities during the pre-cracking and post-cracking stages for horizontally- curved waffle slab structures....
Evaluation of Seismic Isolation Schemes for a Historic Building
The U.S. Court of Appeals Ninth District building originally completed in 1905 with an expansion in 1933, suffered damage during the 1989 Loma Prieta earthquake. The building is currently...
Diagnosing Lateral Strength of Existing Concrete or Masonry Buildings
A research prospectus is presented for improving present methods of structural evaluation for concrete and masonry buildings. Specifically, the proposed research plan is limited to strength...
Seismic Strengthening for Structures in Regions of Low Seismicity
Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently....
Axial Capacity of Concrete Infilled Steel Box Column with Biaxial Bending
The objective of this study was to investigate the feasibility of using the Bresler reciprocal load method to calculate the axial capacity of a concrete infilled steel box column subjected...
An Innovative Connection Detail for High-Rise Buildings
Composite columns consisting of hollow steel tubes filled with high strength concrete have been used in high rise building construction in the USA and Far East Asian countries. The focus...
Composite Beams and Joists
Composite beams and joists used as flexural members in multistory steel-frame buildings are considered. Research results have shown that present design values for headed shear studs, used...
Flexural and Shear Behavior of Combined Concrete and Graphite Epoxy Beams
An experimental and analytical study of six graphite composite beams are presented. Four of the beams incorporated a reinforced concrete slab. The composite action and the effect of concrete...
Strength, Behavior and Repair of Masonry Infills
Results of a series of experiments are presented on seismic performance of unreinforced masonry infill panels. The object of the investigation is to examine the loss of out-of-plane strength...
