| Executive Summary: | The practical application of steel fibre reinforced concrete (SFRC) in thin plate structures such as bridge decks, thin slabs, roofs and thin walls are still limited. Due to the complex loading form and fibre geometry, these thin plate structures are subjected to biaxial stress states, which are different from those of the uniaxial structures such as beams and girders. Therefore, for proper and accurate analysis utilizing SFRC in thin plate structures, constitutive model in compression and tension must be developed, by considering the full biaxial stress effects. Previous studies on SFRC on the effects from the biaxial stresses are still limited. Lack of understanding on its failure criterion may lead to non-conservative design of SFRC, and this gives the motivation to carry out this research. The main aim of this study is to develop the biaxial failure envelope curve for SFRC by experimental method. The experimental test will be carried out in two phases, where the test parameters include the fibre percentage ratio (0.5%, 1.0% and 1.5%) and fibre length (30 mm and 60 mm). In Phase 1, the engineering properties of SFRC are determined. In this phase, all testing are subjected to uniaxial loading, where the finding is important to study the properties and post-cracking behaviour of SFRC. In Phase 2, the biaxial stress test will be carried out in three loading situation: tension-tension, compression-compression and compression-tension. The findings from this phase will develop the full failure envelope of SFRC under biaxial stresses. In order to provide a safe and economic design of thin plate SFRC structures, it is inevitable to have experimental information about the mechanical and fracture properties of the material under various stress states i.e. uniaxial and biaxial, occurring throughout the structure’s service life. |

| Executive Summary: | In spite of organized responsibilities in many building managements, there are still tendency for building defects to occur of which can lead to failure. Some building defects are repairable and some are not. However, there is no formative and systematic building maintenance management system in order to categorise the different type of building defects and/or failures when carrying out the building auditing and inspection. Furthermore, Public Works Department (PWD) and even the local authorities have yet to establish a building maintenance management system to assist in the management of inventory, periodic inspection and maintenance of buildings. The objective of the study is to develop a Standard Operating Procedure (SOP) for Building Condition Assessment (BCA) for the ease of building inspector. In this study, a systematic survey by visual inspection will first be carried out in order to identify the different types of building defects. However, the study is limited to only structural and non-structural components. Following this, a method of assessment will be identify from various local and international organizations in order to get a robust and thorough SOP for BCA. On-site qualitative and quantitative assessment, questionnaires and statistical analysis will be use throughout the study. At the end of the study, a comprehensive guide and checklist for SOP is produce in electronic format, so that a long-term maintenance programs can be addressed for specific needs and conditions of the buildings, and at the same time may reduce the maintenance cost. Industry benefited from the electronic form of BCA by minimizing time and resources when carrying out the building assessment on-site. |
| Project Title: | Building Condition Assessment (BCA) Framework for Heritage Building in Johor Bahru |
| Level: | International |
| Type of Grants: | Foreign University – Hanyang University, Republic of Korea |

| Executive Summary: | This research proposed a standard operating procedure of Building Condition Assessment (BCA) on heritage buildings in Malaysia, assessed based on its maintainability, security, functionality and most importantly, material originality and cultural significance. A number of case studies are conducted to study the acts and regulations of BCA and step-by-step procedures in achieving the ratings of each architectural and structural components condition and its maintenance priority ratings. From the matrix analysis of those ratings, the overall condition of the building is rated from 1 to 5, which indicates from perfect to worst building condition. The study is also aimed to propose a standard operating procedure of BCA by providing a framework of database, which covers the overall process of both assessments starting from collecting data from visual assessment, followed by non-destructive testing for further investigation and the final result of the building condition and rating. One of the expected outcomes is the overall rating of the heritage building as a purpose for future maintenance and rehabilitation, while preserving the cultural heritage resources. From this study, a complete understandable and user-friendly database will be proposed for the ease of the Building Surveyor or assessors in conducting the BCA. |
