Steel circular hollowsections (CHS) have good resistance under tension, compression and torsion loads, considered isolated or combined. Recent researches have been carried out to evaluate the behavior and resistance of these structures. A current use of steel hollow sections is roof trusses, a kind of structure that demands standard procedures and fast assemblage. This work presents an experimental study of a new type of connection called sleeve, developed to attend the assembly process. The connection consists of two tubes internally connected through a third tube with a smaller diameter with passing bolts arranged in line and cross. This connection makes easier the structure assemblage and is aesthetically advantageous if compared to usual flanged connection used in hollow sections. An experimental program of the sleeve connection with bolts in line (along the tube) and crossed at 90◦ was developed. In this work were tested 3 prototypes with staggered bolts to complement previous research and 12 prototypes with crossed bolts. The parameters considered in investigation were tube diameter and thickness and number of bolts. Experimental results lead to identification of failure mode and the resistance of sleeve connection. The analysis of theoretical and experimental data revealed that the dominant failure mode was bending in the bolts, and indicated a reduction in connection resistance that needs to be quantified. For the prototypes with staggered bolts, the analysis also let the development of an expression for the determination of flexural failure in the bolts. The results have demonstrated the viability of this new type of connection, but indicated that all possible failure modes need to be carefully checked. © 2015 Taylor & Francis Group, London.

Modern societal-scale infrastructures (e.g., buildings, roads, railways, and power supplies) that are defined by spatially distributed network structures, concurrent subsystem-level behaviours, distributed control and decision making, and interdependencies among subsystems that are not always well understood. During both Hurricanes Katrina and Sandy, it quickly became evident a disturbance in one system can impact other networks in ways that are both unexpected and undesirable. Such outcomes put engineering designers and urban planners (decision makers) in a tough spot where quantitative decision-making regarding the adequacy of system infrastructure is complicated by the presence of newfound system interactions. This paper takes a first step toward providing designers and planners with computational support for simulation of distributed system behaviours with system-level interactions. We describe an experimental software prototype for distributed event-based system behaviour modelling with ontologies, rules checking and message passing mechanisms. Key features of the software architecture are demonstrated through the development of two scenarios: (1) A family interacting with a school system, and (2) Simulation of adjustments to the Washington DC Metro System schedule in response to a severe storm.

The advancement of renewable energy technology gave rise to the implementation of small wind towers in urban areas. A major problem in predicting the use of such facilities is the difficulty of measuring in micro-regions that suffer different influences of the surrounding environment. Thus a wind tower may be installed where it does not work properly. Fuzzy inference systems try to approach the thinking process of human language allowing for a more assertive decision process. For the development of a fuzzy inference system dealing with this issue it was necessary to determine the variables that most impact on the variation of the wind distribution in micro urban environment as well as using data from automatic weather stations which allow to estimate the wind regime for a macro region. These data are fed in a fuzzy inference system that outputs an adequacy rank for sitting a small wind tower.

Energy Procedia 2015年 74卷 453-461页

Lean concepts, though born in the manufacturing industry, have since made their way to the construction industry. In a broad sense, lean concepts aim at minimizing waste and maximizing value which can be related to cost, quality, and time. These aims are in-line with sustainable construction processes which target reducing the waste (e.g. resource consumption and emissions) in construction activities. As such, lean should not be viewed as a set of tools and techniques, but rather an approach and conceptual framework that can be catered to suit the needs of the process under study. Implementing lean concepts in the building construction sector has been proven challenging due to the uniqueness of each project. In infrastructure projects, such as pavements and bridges, the application of lean concepts is at its infancy stages and thus is still not well assessed and researched. The focus of this study is to investigate the implementation of lean concepts in pavement construction, specifically in the quality assurance/quality control (QA/QC) process. The ultimate objective is to come up with conclusions on how to maximize the value of pavements as dictated by their performance, while minimizing wastes due to inefficient QA/QC.

Floods are among the main types of phenomena associated with socio-economic and environmental damage. Although it occurs public investment and advances in hydro meteorological monitoring and warning systems, the damage is recurring because there are high risks involved. This shows the vulnerability of the city against floods and at the same time, the skills of those affected in live with the risks, while not having conditions Ark them. This study examines the damage related to the historical events of 1983, 1984, 1992 and 2001 in the city of Blumenau (SC), located in southern Brazil. Initially, two approaches have been developed for this evaluation. The first approach was statistically resulting from the application of 387 questionnaires in interviews with residents and merchants of flood areas, and the second approach was economic damage. The results of the two approaches were used in the composition of an evaluation model of tangible damage associated with floods and floods in the city of Blumenau, called MAVEN. The results calculated by the model were considered good, although it presents results with significant discrepancies when applied to extreme hydrometeoro logical events such as the environmental disaster of November 2008, characterized as a result of landslides in large proportion due to the large volume of rainfall without above. One of the results of the model was the need to characterize in detail the input data, since the spatial and temporal peculiarities tend to prevent optimal performance of the MAVIN model. The main conclusion was that the standardization of an evaluation model of damage points (type of MAVIN) can provide greater certainty in determining public policy to minimize future damage and provide good benefits to actuarial calculations for resizing purposes of disaster risks addressed to Insurance Companies.

In the process of transforming animal hide into leather, the hide, which is susceptible to putrefaction, is stabilized. The growing interest in clean technologies and environmental requirements led tanners to increase their efforts to develop chrome-free tanning agents. Among the various tanning options, vegetable tanning is a traditional and recognizable method and, associated with some physicochemical properties, it provides the leather with unique characteristics, retaining the natural flaws and markings. As an organic biodegradable material, it is also environmentally friendly. The vegetable tannins are complex mixtures with tanning action provided by their concentration of phenolic substances that react with collagen materials. This study aimed to investigate the ability of hide's collagen substrate to absorb and fix vegetable tannin of acacia mearnsii at different pH, through the use of especial analytical and experimental methods. In substrates such as collagen powder, bovine hide powder, and bovine hides, was examined the influence of the pH and tannins offers on the absorption and fixation of acacia vegetable tannin. The absorbed tannin content was determined by UV-visible spectroscopy and by the difference of solids contents in the suspension before and after tanning. The analyses of zeta potential allowed for the elucidation of conditions of the tanning process.

This article describes a damage identification methodology based on a genetic algorithm and its application to the numerical model of a railway bridge. The identification method is based on an iterative process that in each iteration compares the values of the bridge's dynamic response for a test damage scenario with the response values for a reference damage scenario. The introduction of damage to the test numerical model is based on the modification of a preselected numerical parameter values. The genetic algorithm allows the identification of damage by minimizing the residue of an objective function constructed from the responses of the test and reference model, and based on the so-called damage indicators. In this study are defined and tested damage indicators based on modal parameters (frequencies and vibration modes) in parameters built from the modal parameters (modal curvatures and flexibility curvatures), and in dynamic responses under action of impulsive loads from frequency response functions (FRFs). The proposed methodology for identifying damage was tested based on a two-dimensional numerical finite element model of a railway bridge including the railway track. The results allowed evaluating the efficiency and reliability of the methodology and of the damage indicators which, in most situations, showed potential in the detection, location and quantification of the severity of the damage.
