“…e results demonstrate that relative displacement is a better response quantity for structural health monitoring of composite bridges. Moreover, Dackermann et al [29] presented a dynamic-based method for evaluating the connection systems of timber composite structures. e proposed dynamic method provided an alternative to traditional static load testing and used vibration measurements to derive a loss of composite action index.…”

This paper presents vibration-based damage detection (VBDD) for testing a steel-concrete composite bridge deck in a laboratory using both model-based and non-model-based methods. Damage that appears on a composite bridge deck may occur either in the service condition or in the loading condition. To verify the efficiency of the dynamic test methods for assessing different damage scenarios, two defect cases were designed in the service condition by removing the connection bolts along half of a steel girder and replacing the boundary conditions, while three damage cases were introduced in the loading condition by increasing the applied load. A static test and a multiple reference impact test (MRIT) were conducted in each case to obtain the corresponding deflection and modal data. For the non-model-based method, modal flexibility and modal flexibility displacement (MFD) were used to detect the location and extent of the damage. The test results showed that the appearance and location of the damage in defect cases and loading conditions can be successfully identified by the MFD values. A finite element (FE) model was rationally selected to represent the dynamic characteristics of the physical model, while four highly sensitive physical parameters were rationally selected using sensitivity analysis. The model updating technique was used to assess the condition of the whole deck in the service condition, including the boundary conditions, connectors, and slab. Using damage functions, Strand7 software was used to conduct FE analysis coupled with the MATLAB application programming interface to update multiple physical parameters. Of the three different FE models used to simulate the behavior of the composite slab, the calculated MFD of the shell-solid FE model was almost identical to the test results, indicating that the performance of the tested composite structure could be accurately predicted by this type of FE model.

The construction industry has become one of the major sources of global greenhouse gas (GHG) emissions. Therefore, low carbon buildings have been assigned for reduction of human impact on the environment. The aim of this research is to decrease the CO2 effect from the building sector by eventually proposing a new structure for Malaysian construction with regard to the needs of this industry. Life cycle assessment (LCA) has been performed to analyze the CO2 emission for the Malaysian residential single family house. Seven different materials or structures have been assessed and the result shows that timber prefabricated post and beam is the best choice due to releasing less CO2 emissions to the atmosphere. However, timber has become almost forgotten as building material for house builders in Malaysia in the last four decades. The alternative building scheme has been made by reinforced steel plate into wooden beam and column and timber wall (S8) to improve the building structure deficiency and load bearing while releasing less CO2 emissions in comparison to other buildings. New structure has been designed by steel plate sandwiched between wood members and held together with bolts in beam and post toward decreasing the percentage of improper design and to improve accuracy in the execution of timber structure. Thus, new scheme (S8) could be advised to house maker and government as a new policy to promote the sustainability in construction sector. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1394–1402, 2018
