Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...
Inelastic Performance of Single-Story Masonry Shear Walls
Twenty-two story-height reinforced masonry shear walls have been tested to examine the influence of the applied axial stress, and the amount of vertical and horizontal reinforcement on...
Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....
Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...
Normalized Damage Index for Evaluation of Buildings
A conceptual model for evaluation of structural damage is developed based on the fundamental idea of demand and capacity. The proposed formulation combines two recognized sources of damage:...
Seismic Vulnerability and Retrofitting of Buildings. Recent Experiences in Mexico City
Measures taken in Mexico City after the 1985 earthquake to evaluate the safety of existing buildings, to strengthen damaged structures and to retrofit those that were considered to need...
Seismic Vulnerability Evaluation in Japan
The state of the art in Japan is reviewed on the evaluation of the seismic capacity of existing low- to mid-rise reinforced concrete buildings, taking into account the different resistance...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...
Collapsible Soils in the Antelope Valley�California
Soils subject to hydroconsolidation, commonly referred to as collapsible soils, have a potential to undergo significant volume reductions upon wetting, with or without additional loading...
Human Factors and Communication Problems in Foundation Engineering
Recent findings in non-engineering fields related to human factors are reviewed with emphasis on communication difficulties. Foundation engineering tasks are discussed in the context of...
Interpretation of Load Tests on Drilled Shafts?Part 1: Axial Compression
Existing interpretation methods for axial compression load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A simplified method,...
Interpretation of Load Tests on Drilled Shafts?Part 2: Axial Uplift
Existing interpretation methods for axial uplift load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A new method, which fulfills...
Interpretation of Load Tests and Drilled Shafts?Part 3: Lateral and Moment
Existing interpretation methods for lateral and moment load tests are reviewed critically, and a qualitative and quantitative comparison is made for selected methods. A new method is proposed...
Reliability in Foundation Engineering Practice
The value and use of reliability concepts in foundation engineering practice are explored, with a focus on two complementary approaches. In the first, macroscopic and action-oriented,...
Low-Level Waste Disposal Design: An Overview
Low-Level radioactive waste disposal is regulated by several agencies. Mixed waste, which is both radioactive and chemically hazardous is regulated by two agencies with potentially different...
A Report on 18 Warning Systems in America
Of all weather related disasters in the United States, floods are the primary cause of death, and most flood related deaths result from flash floods. One of the major changes in flash...
Reliability of Bank Protection Works Subject to Erosion
Sediment movement and changes of bed levels in natural rivers are non-stationary processes. The design of protection works for structures against erosion should account for the time dependency...
Model Study of Side Slope Riprap
Laboratory experiments were conducted in 10-m long channels having 1.5 H : 1 V side slopes protected with a 20.7-mm diameter rock layer 1.5 diameters thick. Four models were tested. In...
Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...
