The scope of work will concentrate on the preparation of application rules for design in modular construction using steel technologies, which takes account of the nature and practicality of the construction system. The application rules will be based on the principles of Eurocode 3 for steel structures, Eurocode 1 for loading (actions) and EN 1090 - Execution of steel structures. This will based on physical tests and supporting finite element analyses (FEA) of the tested systems.
In this Work Package, it is proposed to develop a diverse range of innovative typologies for modular residential buildings. An important task is to understand future demands and therefore to create building typologies that respond to these needs. The building typologies will also take account of the structural characteristics investigated in WP1. This Work Package will involve close participation of architectural practices experienced in modular construction. The scope of work will develop residential building typologies using modular construction, which takes account of the construction system, spatial requirements, Regulations and planning standards in various countries, such as fire safety, circulation space and disabled access.
In this Work Package, various scenarios and intensities of seismic events will be considered which will be modelled statically by progressive ‘failure’ the connections between the modules. Dynamic models will be performed to establish the natural frequency of the assembly of modules taking account of the ‘spring’ connections. The compatibility of equivalent static and dynamic models will be investigated in order to develop design rules for the stability of modular buildings in seismic action. Strategies to prevent collapse of modular buildings in severe seismic events will be evaluated, such as by enhancing the resistance of the connections or by connecting the modules to intermediate ‘strong’ points via a separate structural frame. In high –rise buildings, it may be necessary to introduce stiff braced floors, so that progressive failure of a large number of modules is prevented. This strategy is dependent on the precise building form.
The scope of work in this Work Package will be divided into four parts: • Quantification of the sustainability benefits of the construction process, based on measures such as; site impacts and disruption to the neighbourhood, safety, transport, waste reduction and recycling, use of recycled materials etc. • Quantification of the operational energy benefits of modular construction and particularly comparison of design versus as–built operational energy use and other performance measures, such as over-heating and effective ventilation. • Effective integration of renewable energy technologies in modular construction, which may be part of the module or attached to the modules. • Environmentally conscious design solutions for modular buildings in terms of architecture.
The objective is to improve the acoustic characteristics of the modular systems in compliance with basic regulatory requirements ,and then to achieve 3 and 5 dB improvements in acoustic insulation based on the double layer nature of modular systems, as follows; • Examine the details of the modular systems in terms of control of airborne and impact sound transfer, taking into account the module to module connections • Develop an adapted prediction method for the acoustic design of modular buildings • Carry out laboratory measurements of the acoustic performance of modules relative to adjacent modules • Evaluate the field performances of modular buildings in relation to laboratory measurements, and investigate any significant differences.
The objective of the dissemination task is to publicise the information obtained from the project in terms of: • Architectural information describing the building typologies and details for high-rise and mixed use buildings • Structural design guidance on high-rise and mixed use buildings to Eurocode 3 • Seminars to present the results of the project • Case studies on buildings using the developed technologies • Sustainability guidance on modular construction.
It will also be necessary to manage the exploitation of the results of the project through a specific task, and to publicise the work at appropriate stages of the project and on completion.
To achieve the project objectives (development of new and innovative products to enter the market in a short to medium term) with regard to cost, quality and time, the management tasks will require: • Organizing the activities of the project partners and solving potential conflicts to carry out the project activities in due time according to the project programme. • Acting as the interface between the project participants and the European Commission. • Performing the coordination and organization of the results’ intellectual property. • Coordinating and contributing to the technological transfer of the results.
