When are Loads Taught? A Case Study and National Trends.
Several years ago, structures faculty of the Department of Civil and Architectural Engineering at the University of Wyoming revised their structures courses to meet several new educational...
Where do the Arrows Come From? Evaluating Structural Loads
Two elements of an undergraduate's structural education that are not treated well in most textbooks are (1) the development of correct loads and (2) load modelling-that is, how the load...
Teaching Structural Loading: A Case Study
CVEG 4803: Structural Loading course was formulated three years ago as an undergraduate senior elective course. In this course structural dynamics is introduced for one third of the course....
Experimental Measurements of Dynamic Loads Imposed by Moving Crowds
Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of...
A Probabilistic Approach to the Response of Tall Buildings to Wind Loadings
Tall buildings constructed in recent years are light in weight, flexible and low in damping. This is the consequence of using lighter material with higher strength, and fewer interior...
Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...
Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...
Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...
Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...
Seismic Retrofit of R/C Columns with Inadequate Lap Splices
This paper presents experimental results on the use of rectangular steel jackets to improve the seismic performance of rectangular steel jackets to improve the seismic performance of rectangular...
Seismic Renewal of Civil Infrastructure Systems
Almost all civil infrastructure systems are vulnerable to natural hazards such as earthquakes. The paper presents a broad perspective of the research needs for seismic renewal of the infrastructure...
Analysis of Unstiffened and Stiffened Tubular Members Under External Pressure and Structural Loads
This paper summarizes some important results concerning the ultimate capacity of stiffened and unstiffened tubes under combined loading. Such tubes are candidates for use in offshore structures...
A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...
Review of Cold-Formed Steel Purlin Design
The use of cold-formed steel members as roof purlins for single story industrial and commercial buildings is commonly recognized. These members typically have either a C- or Z-shaped cross...
LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...
What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...
An Application of Inverse Problem Techniques to Spatial Structures
The present paper attempts to give a definition of inverse problems for spatial structures, and to develop a design method to find the optimum configurations and shapes for such structures...
Field Measurements of Tensile Forces on a Spherical Dome Sector Caused by Internal Load of a Granular Product in Storage
Using a number of existing equations developed application to silos, bins, and hoppers, the horizontal load resulting from the stored product can be calculated. In this paper, the physical...
Research and Application of Various Joints of Space Grid Structures in China
This paper introduces the research work results and applications of various joints of space grid structures in China. It also gives out formulas for determining the loading capacity and...
Response of Truss Structures Subjected to Dynamic Loads During Member Failure
