Compressive Resistance

The concept of schifflerization of 90° equal-leg angle is presented and its application in triangular-base latticed steel towers is explained. The similarities and differences between schifflerized angles and regular 90° angles are discussed. The current design practice for schifflerized angles is reviewed and its limitation is highlighted. A design method which includes the effect of the torsional-flexural buckling mode of failure is proposed. For ready use of designers, the factored axial compressive resistances of schifflerized angles are tabulated for both the present and proposed design methods. Key words: buckling, compressive resistance, design criteria, schifflerized angles, stability, standards, steel, struts, towers, guyed towers.

The Uk

Since 2000, design practice in the UK has changed dramatically. Boundaries between design disciplines have dissolved, and many contemporary design studios now defy classification. These studios are reconfiguring the design landscape, yet a uni-disciplinary structure still dominates undergraduate education. This is creating a disconnection between practice and education and posing critical questions for the current design education system. This article outlines the findings of a PhD research study exploring this disconnection, and although situated within the UK, the findings have international relevance. An initial scoping exercise draws on interviews with leading commentators from the UK design sector, examining the evolution of design practice over the past 10 years, and possible future directions for undergraduate education. Findings highlight that UK policy for creative education has placed undergraduate design courses in potential crisis. Arguably, the current university system for design education is outdated. It is now necessary to redefine the skills and processes twenty-first-century designers need. The body of the research is situated within five internationally renowned creative studios which defy classification. In-depth ethnographic studies cross-analyse the creative processes of these studios and their views on education. Findings identify key components of each studio’s processes, while also exploring studio members’ educational experiences, and reflections on future implications for pedagogy. This article argues that this growing disconnect between practice and education calls for existing pedagogic models to be challenged, proposes alternative approaches and highlights the need for policymakers, practitioners and educators to work together to best prepare young designers to meet today’s challenges.

Global warming and extreme weather events reported in the last years have attracted a lot of attention not only in academia and media but also in the shipping industry. Three important questions have been in focus: will occurrence of extreme weather events increase in the future, which geographical locations will be most affected, and to what degree will climate change affect future ship traffic and design of ship structures. Observed and projected changes in wave conditions are expected to have the largest effect on ship design and operations in comparison to other environmental phenomena. The present study briefly summarizes recent investigations addressing changes of significant wave height in the North Atlantic, including the last findings of IPCC (Intergovernmental Panel on Climate Change), and discusses how these changes can be included in environmental description used for ship design. It is also interesting to notice that climate changes resulting in some ocean regions in increase of storm activity (intensity, duration and fetch) and changes of storm tracks may result in secondary effects such as increased frequency of occurrence of abnormal waves, also called rogue or freak waves. This study shows how the scientific findings on climate change and rogue waves can be incorporated in the risk-based approach used in current design practice of tankers, and ships structures in general. Further, it demonstrates the effect of climate change and rogue waves on tanker design, particularly on the safety level of current design practice. Finally, the present paper discusses how structural design of ships can be upgraded to account for climate change and rogue waves but economic consequences do not need to be significant.

Current Design

A method for generating accurate numerical solutions of the exact differential equations describing tension distribution and radial penetration of a flexible V-belt on driveN and driveR sheaves is presented and results are compared with approximate solutions reported in the literature. Analytical approximations for these solutions of higher accuracy than any previously published have been found and are presented. They suggest important modifications of current design practice for belt tensioning and life appraisal.

Analysis Design

An approximate, simple, and reliable method of analysis is presented for an air-supported cylindrical membrane structure. Furthermore, to use this method of analysis for design purposes, a brief description of dominant design loads and its formulation as applied to air-supported structures is also given based on design practice and experiments. Incorporating both the method of analysis and the described design loads, a microcomputer-based program, coded in MS Quickbasic, has been developed, which is simple to use and completely user friendly.First, the reliability of the approach is established by comparing it with available published studies on circular cylindrical air-supported structures, based on rigorous modelling and analysis. Then, several illustrative examples are presented for different heights and spans under various loading combinations as per current design practice. Key words: air-supported membrane, cylindrical, finite displacement, microcomputer based, approximate, analysis, design.

Hinge Zone

In regions, described as plastic hinge zones, in beams and columns, tensile yielding of the reinforcement through flexural action can occur in severe earthquakes. Where the beams and columns are lightly loaded, axially, member elongation can occur. Test results show that axial extensions of the order of several percent of the member depth may be expected. This deformation, which is ignored in current design practice, can have a major influence on the distribution of forces in a structure and its ability to survive without collapse. This paper describes the way in which elongation develops in plastic hinge zones together with the form of load deflection characteristics associated with the development of different types of plastic hinge zone.

Cause Of Failure

The pressure loads applied to yacht hull plating by slamming have been estimated by pressure testing small sections of aluminium hull and comparing the resultant damage with service damage to hulls of similar construction. The structural response of the plating to the pressure load is discussed with reference to current design practice. The design pressures in current use are found to be unrealistically low and the cause of failure has been found to be elastoplastic buckling, rather than bending.
