The paper investigates the influence of the actual behavior of beam-to-column and column base joints on the seismic vulnerability of one storey steel structures. A numerical study was conducted on as-built real steel buildings whose column bases and beam-to-column joints have a semirigid and partial-strength behavior, although they were originally designed as rigid and full strength. Finite element models of the selected buildings were developed, assuming both the theoretical and the actual joint behavior and their seismic performance was investigated through nonlinear time history analyses. Kinematic hysteresis models were assigned to semirigid joints to account for their actual stiffness, nonlinear behavior, and energy dissipation capacity. Then, fragility curves were derived, on both the theoretical and the as-built buildings, for various damage levels, with the aim of comparing the probabilities of ex-ceedance of the selected limit states. © 2023 COMPdYN Proceedings.

In this paper, a numerical study on the response of multi-storey moment-resisting steel frames subjected to seismic actions, accounting for the real behavior of both the beam-to-column joints and the column bases, is presented. Two real benchmark buildings are considered for the purpose. The examined buildings are characterized by beam-to-column joints and column bases with semi-rigid and partial-strength behavior, although they were improperly assumed as rigid and full-strength in the original design process of the frames. In order to appraise how this wrong assumption influenced the building safety, finite element models are set up, first by modelling the joints according to the original design approach and then incl.ding the real stiffness and strength. Nonlinear dynamic analyses are performed and fragility curves for different limit states are obtained, considering the record-to-record variability as main source of uncertainty.

The design of joints of steel frames is often simplified, assuming that they have a fully rigid or ideally pinned behaviour. This wrong assumption is sometimes acquiesced by national technical codes, which mainly focus on the behaviour of simple connections and neglect the role of the joints in terms of global structural behaviour, particularly under lateral loads. In this paper, a numerical study about the evaluation of the influence of partial-strength/semi-rigid joints on the seismic performance of one-storey steel buildings is presented. For this purpose, a population of real steel buildings has been considered, for which column bases and/or beam-to-column joints were originally designed as infinitely resistant/rigid restraints, but that, after the application of the component method, were found to be characterized by a partial-strength/semi-rigid behaviour. Finite element models of the examined buildings were developed, assuming both the theoretical and the actual joint behaviour. Fragility curves were constructed through nonlinear dynamic analyses, so to evaluate the seismic vulnerability of the structures and assess whether they need joint reinforcement, or, otherwise, if they already ensure adequate seismic safety. © 2023 The Authors.

This paper presents a comparison among eight tools commonly used to evaluate the solar irradiation in urban environments. The focus is on the vertical surfaces (i.e., façades). The analysed tools have a large range of applications, from detail.d microclimate studies to large-scale irradiation modelling. The benchmark tests consist of simulations using two conceptual urban designs. Two representative winter and summer days are defined. The results, obtained for the modelling of the shortwave irradiance received on the façades, are discussed together with the observed differences. This work provides an overview of some of the available tools, their features, similarities, and differences as well as a comparison of the modell.d solar irradiation. This work is conducted in the framework of IEA SHC Task 63 "Solar Neighborhood Planning" where experts from five countries, in six universities, two companies and one research institute have been engaged. © 2021.

The water vapor condensation in the HVAC system chillers can be employed to increase the sustainable use of resources by using the condensed water for domestic consumption. Preliminary investigation on a design of an integrated HVAC system for the air conditioning of a hotel combined with water production is presented. The calculations are referred to the climatic conditions of the Arab Emirates coast. The preliminary calculations show that the produced water could be efficiently used for various destinations and, in some cases, its treatment could be finalized to produce drinking water.

Production of Water from the Air: The Environmental Sustainability of Air-conditioning Systems through a More Intelligent Use of Resources. The Advantages of an Integrated System

引用

Energy Procedia 2015年 78卷 1153-1158页

The possibility of extracting water from air is an activity that has been studied recently, especially with the purpose of producing it for emergencies or exceptional events, when drinking water is not temporarily available. Several mobile/transportable equipment have been designed in order to producing water from the air: they can be placed, if necessary, in appropriate locations where water is needed. Water extraction can be done with different technologies, one of which is represented by cooling water below the dew point, to cause condensation of the vapour content of the air. The system efficiency, normally calculated in standard conditions, should be tested in the climatic conditions in which it will be used, because water production varies significantly with temperature and air water vapour content. An interesting solution may be an equipment for water extraction that contemporarily uses the cool.d air for refrigeration, which consists in a combined HVAC system for the dual purpose of water production and air-conditioning. A case study represented by this kind of HVAC system, for a hotel in a sub-tropical arid climate, is proposed in this paper, to demonstrate the advantages of this solution. To this aim, the comparison is made between a typical HVAC system and an integrated air conditioning system, optimized for water production from air, in order to highlight advantages and capabilities of the second one.

The concept of living stability is inherent in the sedentary lifestyle of living for a human being. In the past, difficulties of movement and geographical barriers have produced the interaction between the identity of people and the place inhabited: the genius loci. In the globalization millennium, the possibility of unlimited travel has l.d to the reinvention of nomadism and the consequent change in the design and requirements of the house. Natural.disasters always require, as a result, building temporary shelters that allow people to shelter, waiting for the restoration to the situation prior the tragedy. Being an individual as a citizen of the world, nowadays, the genius loci is expressed in temporary housing, which is connected to the usual way of life and not to an unusual situation, limited to a period of time waiting for a change. When drastically reducing the amount of time that housing stands inside a certain area, it is necessary that it does not cause environmental.damage. In light of these thoughts, it is possible to define the problems associated with temporariness and the requirements that allow one to solve them. A feasibility study is herewith proposed, for a temporary structure of housing, consisting of a steel structure with articulated dry joints, inside which are inserted, by the aid of a sl.ding system, three-dimensional prefabricated modules in steel and wood, like a system of chest of drawers. Our preliminary study of materials, building techniques, transportation and assembly systems, has allowed us to design an opened and infinitely expandable building unit. © 2014 WIT Press.

After an earthquake, temporary structures play a key role in the immediate emergency and during the reconstruction. In the territory of l'Aquila, after the earthquake of the 6th April 2009, tents were used in the first emergency to provide immediate shelter to the population and prefabricated structures have been used later to accommodate the population during the longest stage of the reconstruction. But there is another type of temporariness too, linked to the securing of the damaged buildings and aimed to preserve the historical and artistic value and ensure the safety of road and workers during the reconstruction period. The secure systems use temporary devices, consisting mainly of tubular scaffoldings, multi-directional systems, systems in wood, systems with metal profiles and steel cables, polyester clamps. These systems are used interchangeably according to the function they perform, flexibility, time and cost of installation. during the reconstruction phase safety systems are disassembl.d, progressively generating an enormous amount of waste materials. For these materials it has not been planned a second lifecycle and disposal has a high environmental impact. It is proposed the reuse of these waste materials at zero distance. The purpose is to obtain environmental, logistic and economic advantages. Reuse provides a function change under the temporary, from safety systems to building systems, aimed to the construction of temporary structures, which, in the reconstruction phase, simplify site organization and, in the post-reconstruction phase, restructure public and private spaces. © 2014 WIT Press.

Numerical simulation on natural ventilation in a real estate in high-density city

Natural ventilation is an efficient way to keep residential building safe and comfortable. In many high-density populated cities, to meet the housing demand of citizens, a large number of high-rise residential towers are being built. When buildings are closely sited, the influence of adjacent buildings on the availability of cross ventilation becomes a critical building design consideration. The paper reports on the results of CFd (Computational Fluid dynamics) simulation studies on such effects based on a real estate in Hong Kong that comprised an array of building blocks. The result shows that cross ventilation in buildings downstream of other buildings would be much reduced, especially when the buildings were aligned facing the wind direction, and when the spaces between buildings were small. Shortening the upstream buildings and laying out the buildings in a staggered pattern would significantly improve cross ventilation in the downstream buildings.
