Parking is often a controversial topic. Truck parking, which has reverberations on land use and economic development, was brought to the forefront through TEA-21 Section 4027 that required the Federal Highway Administration to analyze commercial vehicle parking along highways and the Interstate highway system. This paper argues that varying methodologies yield different findings in the assessment of truck parking availability. To examine the impact of different methods on assessing truck parking availability, the paper includes a review of literature, a discussion of methodologies, a case study from Nebraska, and a discussion of planning implications.

In this paper, the development of an original and timeefficient measurement device is proposed for the detailed investigation of the daylight distribution within buildings. It is meant to be used for two kinds of applications: - to assess the sunlight distribution inside scale models in an automated way so as to serve as a design and educational tool for architects and students and help them find solutions to improve the sunlight distribution within their building projects. - to achieve time-efficient bidirectional goniophotometric measurements of materials, typically used for innovative fenestration systems such as solar blinds, advanced glazing or coatings and daylight-redirecting devices, as well as energy-efficient artificial lighting components like luminaires reflectors e.g. The functioning principle of the device in both configurations is explained here and its early stages of development are presented: design and construction of the mechanical platform, command interface prototype and characteristics of the light detection system.

Implementation of advanced analysis method for steel-framed structures under fire conditions

FIRE SAFETY JOURNAL 2005年第4期40卷 339-366页

作者： Landesmann, A Batista, EDM Alves, JLD Univ Fed Rio de Janeiro Architecture & Urbanism Fac Dept Struct Rio De Janeiro Brazil Univ Fed Rio de Janeiro COPPE Civil Engn Program BR-21945 Rio De Janeiro Brazil

This paper is concerned with the development of an advanced analysis numerical tool capable of estimating the inelastic large-displacement behaviour of plane steel-framed structures under fire conditions. A non-linear transient heat transfer analysis is performed on the basis of the finite element method (FEM), following the main guidelines proposed by the European Code for steel structures under fire conditions. The computational analysis program is used to assess the structural load-bearing functions and to estimate the structural behaviour and the corresponding time-resistance period. The original refined plastic hinge method is extended for fire design analysis considering both tangent modulus model and inelastic stiffness degradation concepts in the developed computational program. A tangent modulus model is developed for the European column buckling-curve for fire condition. A gradual inelastic surface is proposed as a function of the temperature and the loading combination. The results obtained are compared with those from an FEM computational program and those from the Eurocode simplified design recommendations. The benefits of using steel ductility in the current design of fire-unprotected structures are outlined. (c) 2005 Elsevier Ltd. All rights reserved.

The worst of all worlds: Los Angeles, California, and the emerging reality of dense sprawl

Transportation Research Record 2005年第1902期1902卷 1-9页

Los Angeles, California, is generally considered the archetypal sprawling metropolis. Yet traditional measures equate sprawl with low population density, and Los Angeles is among the densest and thereby the least sprawling cities in the United States. How can this apparent paradox be explained? This paper argues that the answer lies in the fact that Los Angeles exhibits a comparatively even distribution of population throughout its urbanized area. As a result, the city suffers from many consequences of high population density, including extreme traffic congestion, poor air quality, and high housing prices, while offering its residents few benefits that typically accompany this density, including fast and effective public transit, vibrant street life, and tightly knit urban neighborhoods. The city's unique combination of high average population density with little differentiation in the distribution of population might best be characterized as dense sprawl, a condition that embodies the worst of urban and suburban worlds. This paper uses Gini coefficients to illustrate variation in population density and then considers a number of indicators - most relating either to the provision of transportation infrastructure or to travel behavior - that demonstrate the effects of low-variation population distribution on the quality of urban life in Los Angeles. This approach offers researchers, practitioners, and policy makers in Los Angeles and in smaller cities that are evolving in similar ways a useful and user-friendly tool for identifying, explaining, measuring, and addressing the most problematic aspects of sprawl.

The creation of a new graduate program in Product-architecture, that fuses the design culture normally associated with architecture and industrial design with the engineering institution, has presented the opportunity to better prepare students for a paradigm in which design, engineering and its application merge as an interdisciplinary, collaborative endeavor. In turn this graduate program has been a catalyst to draw in undergraduates in traditional engineering disciplines to this new mode in higher education that also bridges the gap between: undergraduate and graduate education, visual design and engineering disciplines and the academic and professional setting. At the heart of this new approach is the effective use of Information Technology. This is illustrated through a project to design a museum building and multimedia exhibition to display a supersonic Concorde aircraft. The design of the building and of the interactive, multi-media exhibit take cues and content from engineering analysis of the aircraft design as it relates to sub-sonic and supersonic flight. © 2005 IEEE.

2005 ASEE Annual Conference and Exposition: The Changing Landscape of Engineering and Technology Education in a Global World

Civil engineering education should be the primary supplier of engineers to address the engineering needs of the Urban Infrastructure. The Urban Infrastructure (UI) includes the distribution systems for the movement of people, goods and information. In its broadest sense, the infrastructure includes the systems of roadways, water supply, waste disposal, energy distribution (gas and electricity), communication networks (wired and wireless) and myriad subsystems that are necessary to provide a quality environment. The engineer is an essential member of the team of professionals that are responsible for the planning, design, construction and operation of efficient, effective, safe and secure facilities. The Civil Engineering discipline is the appropriate professional arena to meet these needs and civil engineering education is the appropriate educational foundation to prepare students to serve as engineers for the Urban Infrastructure. This paper presents some of the current problems associated with the urban infrastructure and suggests the role civil engineering education could play in addressing the educational requirements necessary for one wishing to "solve" the engineering problems of the urban environment.

A real options model for valuing flexible space

引用

JOURNAL OF CORPORATE REAL ESTATE 2005年第1期7卷 34-+页

作者： Greden, Lara Glicksman, Leon MIT Bldg Technol Program 77 Massachusetts Ave5-418 Cambridge MA 02139 USA MIT Bldg Technol & Mech Engn Cambridge MA 02139 USA MIT Bldg Technol Program Dept Architecture Cambridge MA 02139 USA

The continuous need for change in corporate real estate spaces warrants consideration of flexibility in new space design. To help decision makers invest more effectively in physical infrastructure and its ability to evolve, a formal method of identifying and valuing flexibility is developed. A model, based on real options techniques for valuing managerial flexibility, is constructed to answer the following question: how much is it worth to invest in a space that could be renovated to office space for a specified renovation cost in the future? Decision makers can use the option valuation results to determine whether the initial design and construction costs to achieve flexibility are justifiable. The transparent model is intended to be accessible to design teams in practice. It is an improvement on net present value and first-cost based decision-making techniques in that it explicitly accounts for uncertainty and for the ability of managers to make a rational future decision (between renting and renovating). The model considers three sources of uncertainty: the market price of rent for office space (as measured by volatility);date of space need;and amount of space need. Input values and/or probability distributions are needed for these variables. The model is constructed using a binomial lattice technique and Monte Carlo simulation. Results are given in a format that allows for comparison with cost estimates of physical architectural designs. For example, in a case study where current five-year office-space leases are estimated at US$98 per square foot and 0.39 annual volatility and the mean amount of space needed in the future is 50 per cent of the total, the real options valuation suggests that it is worth up to US$40 per square foot in initial investment expenses to achieve a space that could be renovated to office space for US$25 per square foot within the next eight years. The concept of addressing risk through 'flexible design' and analysing the value of flexib

The 20th century saw a constant search towards lightweight constructions, which tends to go against good sound insulated partitions. Particularly in Brazil this is an important issue, as there is no building regulations concerning acoustic comfort and, therefore, builders target economical goals only. This paper proposes an analysis of the sound insulation performance of Brazilian houses along the centuries. First, a survey of the most important and typical constructions for different periods of Brazilian history is shown. Subsequently, analytical prediction of the sound insulation of their components are performed and evaluated along a timeline. It is demonstrated and quantified the exponential decrease in the building components performance. The aspects that collaborate to keep the situation unchanged are discussed and possible ways out proposed.
