Creep Modelling for Masonry under Plane Strain
A computational procedure based on the principle of superposition to estimate creep strains in composite masonry walls is developed and presented in this paper. This development is based...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Attached Scientific Computers in Structural Analysis
The design and analysis process is explored in terms of its requirements for user decision-making and interaction. This is presented as a three-phase procedure: (1) the engineer developing...
Equation Solving on a Parallel Computer
The application of computers to the analysis of large structural systems is examined. The analysis procedure is presented as three distinct phases: (1) element formulation, (2) equation...
Accuracy Control of Finite Element Analysis of Articulated Structures
An examination of the properties of two-node element models leads to data establishing the acceptable choices in discretization to insure the accuracy of finite element analysis of articulated...
A Perspective on Engineering Computing
Computing in engineering seems to be evolving very rapidly and yet the data shows that it frequently takes twenty years before a viable concept becomes widely available. Economics is the...
The Mexican Earthquake: A Firsthand Report
The Mexican earthquake of September 19, 1985 was most peculiar, because of the combination of its intensity, regularity, and duration. No other earthquake has had an intensity of IX, at...
Liability: Problem or Crisis?
Engineering firms are being hit with liability insurance rate increases of 30%, 50% or more. Deductibles are being raised and the maximum coverage is being decreased. Some firms cannot...
Tiedback Walls Untie Intersection
The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22...
Spanning Urban Obstacles
Extension of Pittsburgh's Crosstown Expressway is a � mile portion of a massive $500 million urban highway now under construction. The extension is a complex of five roadways...
Scenic Squeeze
Constructing a four-lane dual highway through the 12 miles of Colorado's Glenwood Canyon involves several engineering innovations: cantilevered roadways, unusual retaining...
What to Do When a Failure Occurs
When a major building problem involving structural failure occurs, action should begin immediately to determine the damage or failure and detect the underlying problem. This paper will...
An Historical Perspective of Failures of Civil Engineering Works
The blight of failures has smitten civil engineering works since ancient times. An examination of historic cases reveals relationships to contemporary cases that are useful in guiding...
Failure Classifications
A detailed description of the failure classification with respect to the constructed facilities is presented. Author is of the opinion that most reports of failure even of an extensive...
Data Collection and Information Dissemination: Current Efforts and Challenges
The need for the civil engineering community to collect and disseminate information on failures has been discussed widely. It appears that in recent years our profession's reluctance to...
Quality Assurance/Quality Control: Alternative Approaches to Reduce Failures
Efforts to achieve quality on construction projects usually center around code-compliant design, thorough specifications, and careful inspection. The alarming increase in both the frequency...
Excavation in Hard Clays of the Keuper Formation
For the construction of a lock on the Main-Danube-Canal in South Germany a 30 m deep cut had to be excavated in the overconsolidated clays and claystones of the Keuper formation. The strength...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Seismic Risk Analysis of LNG Storage Tanks
This paper presents an approach to the seismic safety review of existing LNG storage tanks. The approach considers the seismic hazards from ground motion, surface fault rupture, and soil...
A Case Study of the Behavior of Seaport Facilities During the 1978 Miyagi-Ken-Oki Earthquake
This paper assesses seismic response characteristics of seaport facilities during the 1978 Miyagi-Ken-Oki earthquake by (a) compiling and assessing documented information from post-earthquake...
