Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Performance of Steel Sheet Pile Cellular Cofferdams
Steel sheet pile cells are often used as construction cofferdams for structures to be constructed in rivers. Examples of this type of construction include locks and dams, pumping stations,...
Remote Automatic Data Acquisition Systems
Personal computers have been used on two projects to monitor peformance of structures in an automatically triggered mode. In both cases a local PC is used to continually monitor a triggering...
Pressure Measuring System for Wind Loads
A project to acquire wind and building surface pressure data in the field is continuing at Texas Tech University. A test building of dimensions 30 ? 45 ? 13 ft (9.1 ? 13.7 ? 4.0 m) and...
Instrumentation of the Shenyang T.V. Tower
The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced...
The Measurement of Structural Deflections
A basic parameter to be determined when assessing the performance of structures is the stiffness. This involves the measurement of static and/or dynamic deflections at representative locations...
Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...
On the Analysis of Viscoelastic Plane Frames
Since its foundation on 1986 the Computational Mechanics Laboratory at the Polytechnic School of Sao Paulo has often been asked for non-linear stability analysis of wood and concrete structures....
Discrete Field Stability Analysis of Latticed Towers
The design of latticed towers is often controlled by the stability of the overall system as opposed to local member buckling. The purpose of this paper is to develop an elastic stability...
Why Bifurcation: A Study of a Reticulated Dome
Numerical results for a hexagonal lattice dome subjected to uniform gravity loading are presented. We demonstrate that a perfect nonlinear bifurcation analysis plays a crucial role in...
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...
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
Nonlinear Finite Element Analysis of Experiments on Two-Story Reinforced Masonry Shear Walls
Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation...
Use of Experimental Data to Develop Probable Behavior
The intent of this paper is to present results of research that studies the performance of the University of Colorado walls tested by Professor Benson Shing. These walls would be classified...
Influence of Nonlinear Models on Dynamic Displacements
This research is a part of an ongoing multi-year program that is sponsored by the National Science Foundation and conducted under the TCCMAR (Technical Coordinating Committee for Masonry...
