“…Some researchers have run a decision-making system to identify the best pneumatic formwork textile (Nemati et al, 2017). Tests illustrated that the usage of Barrateen, a high density polyethylene or polypropylene unbalance woven fabric coated by low density polyethylene is the optimized decision for fabric formwork in the created system ( Fig.…”

Immediate aid to survivors of a natural disaster is the keynote to crisis management. Providing temporary access is one of the most important principles of immediate relief. However, in the postdisaster conditions, it is not possible to use road construction machinery, especially in rural areas. Therefore, in this study, the feasibility of using a Rapid Assembly Building (RAB) system for the temporary pavement with the possibility of rapid construction, which follows the natural topography of the place, is investigated. The introduced system consists of a high-density polyurethane (PUR) foam core as well as two continuous layers of high-density polyethylene (HDPE) facings. For this purpose, the mechanical properties of the materials and composite pavement were determined by a series of laboratory tests. Then, the mechanical performance and bearing behaviour of an element of the presented pavement system was numerically modelled under AASHTO loading. Since in the post-disaster situation, it is not possible to establish the subgrade, an un-compacted subgrade is used for modelling. The results show that this system can be used well in post-disaster situations to provide a rapid, safe, yet robust road without any permanent deformation.

“…There are two general types of fabric formworks: Slack-sheet mold and energized (tensioned) formwork sheets [28]. Each type of fabric distributes force slightly differently depending on the material it is made of and the nature of its internal structures.…”

Development of an Innovative Modular Foam-Filled Panelized System for Rapidly Assembled Postdisaster Housing

Abstract:In this paper, the development process of a deployable modular sandwich panelized system for rapid-assembly building construction is presented, and its structural performance under some different action effects is investigated. This system, which includes an innovative sandwich panel and its integrated connections, can be used as structural walls and floors in quickly-assembled postdisaster housing, as well as load-bearing panels for prefabricated modular construction and semipermanent buildings. Panels and connections are composed of a pneumatic fabric formwork, and two 3D high-density polyethylene (HDPE) sheets as the skins, filled with high-density rigid polyurethane (PU) foam as the core. HDPE sheets manufactured with a studded surface considerably enhance stress distribution, buckling performance, and delamination strength of the sandwich panel under various loading conditions. The load-carrying behavior of the system in accordance with some American Society for Testing and Materials (ASTM) standards is presented here. The results show the system satisfies the codes' criteria regarding semipermanent housing.

A recent study has presented three main sets of decision criteria that help to identify the appropriate housing system for adoption, which are the structural, contextual and behavioral factors [1].…”

The evaluation of housing system in order to make the effective decision for application in housing construction has been a challenge for many developing countries. This study examines the novel approach to evaluate and select the industrialized housing system (IHS) that is appropriate for adoption in the rapid housing development project in Addis Ababa, Ethiopia. The method applied in this study comprises critical literature review, experts' interview and questionnaire survey within the Ethiopian construction industry. Data obtained was analyzed using an analytical hierarchy process research technique and an Expert Choice Comparison software platform. The findings revealed that affordability, quality, and innovation are the most important attributes to be considered for decision-making. In addition, semi-industrialized precast concrete systems are preferable for application cost-effective large-scale housing development. All stakeholders involved in housing development can apply the decision-factors and method used in this study in order to make effective decisions.
