Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
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...
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...
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...
Fire Retardant Treated Wood
The paper explains how FRTW chemicals react with combustible gases. It describes the two types into which FRTW is divided. Misconceptions about FRTW are also addressed....
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...
The Effective Use of Fire Ratings
Any consideration of components for construction must take into account the performance of those components when they are exposed to fire. Codes, standards, and fire ratings provide some...
Vortex Shedding Induced Fatigue Fracture of Mast Tower
The fracture of a pair of 60m high circular steel masts is investigated. The design criteria and fabrication practices are reviewed. The cause of failure is related to the fatigued condition...
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....
Dynamic In-Plane Racking Tests of Curtain Wall Glass Components
This paper is concerned with the seismic performance of 'architectural.' or 'non-structural' building elements such as glass elements in curtain wall systems. A pilot study was undertaken...
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...
Testing of Concrete Permeability for Durability Evaluation
Field and laboratory permeability tests are being performed to evaluate the durability of concrete in Florida. These tests are part of an extensive research program to develop a durability...
Nondestructive Evaluation of Timber
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining...
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...
