Reinforced Shotcrete Linings as Part of an Integrated Support System Used in a High Stress Mining Environment
Shabanie and King Mines are situated in the Southern part of Zimbabwe, some 60 km apart and approximately 200 km east of Bulawayo. They are the largest underground operations in Zimbabwe...
Integration of a Municipal Pavement Management System with a Geographic Information System
This paper describes the use of a Pavement Management System (PMS), and the integration of the pavement condition data with a Geographic Information System (GIS). In June 1988, the Pavement...
Spreadsheet Pavement Management Systems for Local Roads
Changes in administration and funding levels at the local government level are continuing to illustrate the need for information systems to aid the county engineer or public works director....
Seismic Design Criteria for Transporation Structures
Presented is a discussion focusing on two critical issues which must be resolved when setting seismic design criteria for important transportation structures such as those supporting elevated...
Controlling the Seismic Behavior of Precast Concrete
Precast concrete has, through the years the years, acquired a bad reputation insofar as its ability to withstand earthquake is concerned. This reputation, though reasonably based, is not...
Design Criteria for Seismic Connections in Precast Concrete
The seismic behavior of precast concrete is contrasted with that of cast-in-place and the conditions that precast must satisfy are reviewed. Design criteria and possible strategies for...
Ductile Connections for Precast Concrete Frame Systems
This paper describes a research program to investigate the behavior of ductile connections between precast beam-column elements. The objectives of the program are to provide rational design...
Seismic Performance Behavior of Precast Concrete Beam-Column Joints
The experimental test program being conducted at the National Institute of Standards and Technology on 1/3-scale model precast concrete beam-to-column connections is summarized. The objective...
Seismic Response of Average High-Rise Building Structions in Japan
Dynamic characteristic models, representing average high-rise building structures in Japan, have been established through the regression analyses utilizing review documents of seismic...
Seismic Collapse Assessment of Reinforced Concrete Building
In this paper collapse analysis of reinforced concrete frame structures with and without brick infilled walls under a severe earthquake is developed. Because the structural element in...
Large-Scale Earthquake Simulator Study of the Tohoku University Base-Isolated Building
This paper describes a series of earthquake simulator tests of a 1/2.5-scale, base-isolated, three-story, reinforced-concrete building. Three different types of elastomeric seismic isolation...
Earthquake Resistant Design and Construction of Reinforced Concrete Buildings. The Practice in Mexico After 1985
The evolution of the design and construction practice of reinforced concrete buildings in Mexico is presented in terms of materials, structural systems, member design and reinforcement...
Damage Assessment for Reinforced Concrete Buildings with Shear Walls
This paper tries to establish the analytical method of damage assessment for R.C. buildings with shear walls before or after earthquake. Incremental nonlinear spectrum analysis, using...
Welded Wire Confinement Grids
The invention of a new way to reinforce concrete using high strength welded wire grids, (WWG) increases its earthquake resistance by improved ductility and also opens the way for vast...
Seismic Strengthening of R/C Columns Using Steel Jackets
This paper presents experimental results on the use of steel collars and steel jackets as a retrofitting system to improve the seismic performance of short rectangular reinforced concrete...
Use of Eccentric Steel Bracing for Strengthening of R/C Frames
This paper presents preliminary results of ongoing research investigating the feasibility of steel eccentrically braced frames (EBFs) for seismic retrofit of reinforced concrete frames....
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...
Earthquake Strengthening of a Twelve Story Non-Ductile Concrete Frame Building with Unreinforced Masonry Using Displacement Control Criterion
The structural concern with the Cooper Arms Apartment building when subjected to ground shaking was the in-plane and out-of-plane forces on the infill and consequences of the infill resisting...
Investigation of a Failed Concrete Joist System
The failure and distress of concrete joists contained in the promenade roof deck of a one-story, college, lecture hall building initiated an extensive investigation to determine the cause...
