Application of plastic design in steel table shelters
One of the initial applications of plastic theory of structures was the Morrison Shelter, an indoor air raid shelter designed by John Fleetwood Baker (1901 - 1985) during the Second World War to protect British civilians from unrelenting German air raids. Baker integrated his previous work on …

A program for the automatic plastic design and analysis of plane steel frames
… for more efficient and realistic structural design of plane steel frames has brought plastic methods of analysis to the fore. Though not commonly used in South Africa, plastic methods have been adopted elsewhere, particularly in the United States. An incremental approach is presented, leading …

O teorema da acomodação e suas aplicações
In this work, the basic concepts related to the plastic design of structures are reviewed. The advantages and some methods of the plastic design are presented. The shake-down problem is studied. The tests of metalic frames carried out by NEAL and SYMONDS are shown and the shake-down theorem is …

Dimensionamento plástico de edifícios de andares múltiplos, em aço
This work presents a review of the theory of plastic design of multistory steel frames and develops a computer program to implement the automatic design of column, girders and bracings. The plastic design utilizes the ductility, which is a inherent structural steel property, and the redistribution …

Minimum weight design of a multistory frame
Developing a rational method of design has long been the goal of structural engineering. For steel structures, through the development of plastic design and electronic computation, this now seems possible. Several methods have been proposed within the last five years, and one method has been …

Análise elasto-plástica de quadros tridimensionais
The objective of this work is an elastic-plastic analysis of space frames with constant cross section. The analysis is made by the displacement method and applied the concept of the plastic design, determine the mechanism of rupture and the ultimate load. Emphasis is given to the automatic …

A new ultimate limit state approach to the design of prestressed concrete beams
The present approach to the design of prestressed beams is antiquated and time consuming. Neither SLS or ULS requirements are satisfied directly. There is a need for a new approach using plastic principles to design the prestressing requirements at ULS considering a whole span at a time, with …

The effects of impact loading on reinforced concrete panels
… or more of the other damage criteria. An Elasto-Plastic Design Method was developed and used in the analysis. The method is described in Chapter 8 and is given as a simplified method to design panels for impact loading.

Structural design of shallow masonry domes
… in northern India) spanning solution for these designs. Over the same time period, local artisans in the Muzzafarnagar region of Uttar Pradesh in northern India have combined shallow brick vaulting techniques with an RCC tension ring as a small to medium scale spanning solution. While these …

Strength characterization of wood to wood connections using stress field analysis
… usage are two dominant aspects in structural design. As a building material, timber presents a cheap, renewable option. However, current practice favors steel connections for wood structures. Wood to wood connections offer a solution to the minimization of steel connections. While some …

Stability analysis of light gauge steel members using the finite element method and the generalized beam theory
… steel members. It has been found that the AISI design approach with elastic bucking stresses obtained using GBT can be used to correctly predict the strength of compression thin-walled columns. Three different types of widely used light gauge steel members, namely rack columns, purlins and …

Modification of a biosand filter in the northern region of Ghana
Four local plastic design (LPD) BSFs were constructed in Northern Region, Ghana, to test and evaluate an experimental modification of the LPD BSF for treatment of highly turbid water. Modifications of the LPD BSFs were made in order to provide an additional "biolayer," the core layer of a BSF where …

Zusammenwirken von Beton und Stahlprofil bei kammerbetonierten Verbundträgern
… which is required for the high strength steel to plasticize. The load carrying behavior of the concrete encasement is characterized by a three-dimensional stress condition where the bearable compressive strains are increased significantly. By varying the degree of shear connection of the concrete …

ANALYSIS AND DESIGN OF EXCAVATION SUPPORT SYSTEM IN SOFT CLAY
Conventional design procedures for deep excavations in soft clay in Singapore are not always adequate. Consequently, difficulties such as large strut loads and excessive ground movements are often encountered. Therefore, a method was proposed for the design of excavation support system in soft …

Strength and Ductility of Concrete Cylinders Confined with Fiber Metal Laminate Composites
… and undesirable behaviors that are mitigated by design codes through strict strain limits. Because FRP is designed for very low strain levels to prevent brittle rupture and unpredictable debonding, buildings and bridges are strengthened in such a way that restricts their energy dissipation …
