Abstract

The importance of understanding the performance of a building in a holistic sense is undeniable. This paper presents a method of total building performance evaluation, which has been widely used in many developed countries including Singapore. An office building with apartment and commercial retails called “intelligent building” is selected for building diagnosis. The occupant surveys and physical walkthroughs are carried out as subjective evaluations, while some objective measurements of indoor air quality and visual quality are also introduced in this study. The results indicate that generally, the occupants are satisfied with the quality of the building despite some insignificant indoor air quality and visual symptoms due to low temperature and glare problem in the office.

Abstract

The outrigger and belt truss system is commonly used as one of the structural system to effectively control the excessive drift due to lateral load, so that, during small or medium lateral load due to either wind or earthquake load, the risk of structural and non-structural damage can be minimized. For high-rise buildings, particularly in seismic active zone or wind load dominant, this system can be chosen as an appropriate structure. This paper studies the use of outrigger and belt truss system for high-rise concrete building subjected to wind or earthquake load. Eight 40storey two dimensional models of outrigger and belt truss system are subjected to wind load; and five 60storey three dimensional models are subjected to earthquake load, analyzed and compared to find the lateral displacement reduction related to the outrigger and belt system location. For the two dimensional 40storey model, 65% maximum displacement reduction can be achieved by providing first outrigger at the top and second outrigger at the middle of the structure height. For the three dimensional 60storey structural model subjected to the earthquake load, about 18 % reduction in maximum displacement can be achieved with optimum location of the outrigger truss placed at the top and the 33rd level.

Abstract

In developing countries, building maintenance technology is currently vastly underrated and ignored by owners, managers, and professionals. The building and construction authority of Singapore (BCA) has identified that the complaints about building defects have gone up in recent years with common problems such as leaky roof and walls, floor defect, and improper outlet pipe. This paper presents a brief description on building defect in use for commercial building as well as residential buildings in Singapore. The main objective is to highlight the important problems and suggest a greater participation of professionals in building maintenance. It also provides some site investigations photographs of various defects, which is expected to be useful for builders, architects, and others who deal with building materials.
