Structural assessment is the primary method used to assess strength and stability of buildings or infrastructures in various projects including structural renovation and structural inspection. The information acquired through the structural assessment such as compressive strength or rebar position is crucial in the design process.
Structural Health Monitoring & Evaluation is used to track and report on the overall conditions of structural damages which may result from the deterioration of construction materials, or from exposure to stronger forces or heavier loads than those specified in the designs. Structural health monitoring can be used during the early stages of structural restoration and modification. Such monitoring can help reduce the cost of maintenance and also increase stability and safety of a given structure.
Load Carrying Capacity Testing (Load Testing) is an approach used to assess the strength of a given structure by means of real-load installation. Our Load Testing can assess vertical load capacity which is normally affected by the weight of the structure itself and items on the structural layers, and can also assess load capacity as affected by various forces including tension force, compression force and pull-out force. During the test, the deformations of a given structure will be monitored.
Load Carrying Capacity Analysis is used to assess load carrying capacity of structural members such as slabs, beams and columns. The analysis employs finite element analysis software. This service is most suitable for structures with complete construction details which are a crucial factor for accurate analysis. However, Load Testing will be more appropriate if there are missing construction details.
This service is used for structural performance checks, suitable for large structures e.g. high-rise buildings and long-span bridges, of which the vibration signal can be detected clearly. Since the stiffness to mass ratios of these structures are quite low, they exhibit the characteristic of long vibration periods (low frequency) which requires a special type of accelerometers in the measurement process. This approach does not require real-load installation since the ambient vibration response (response to random vibration) will be measured.
