    This research studies the lateral buckling behavior in truss and lateral buckling coefficient of truss. Lateral buckling analysis of truss is performed by simulating the structural model with both end supports being pinned and roller-supports. The analysis is indirectly conducted using Elastic Theory to evaluate the length of lateral buckling by calculating the determinant of the Matrix [K]. Results from the analysis are marginally different from those obtained from finite element program and are considerably less than those obtained from Eurocode standard. This can be concluded that using elastic theory to evaluate lateral buckling coefficient of truss member will result in more economical section.

    This study proposed the comparative analysis of city planning and land use change by using remote sensing and GIS in Bangkok, Thailand. Bangkok had been developed and faced many land use problems. If the problems were not controlled, it will cause more problems in the future. Therefore, this study suggested the solution to solve occurring land use problems in Bangkok. Which, remote sensing was used to do the land survey and automatically map urban land cover from Landsat time-series satellite imagery. Then, the change of urban area and Bangkok Comprehensive Plan were compared by GIS. And, the results showed that urban area in Bangkok increased 403.99 km<sup>2</sup> over the past 21 years. While rural and agricultural zone in Bangkok Comprehensive Plan decreased due to residential area expansion. So, Area Division System and the district plan from urban planning system of Japan can solve the problems by developing the city and controlling urban areas expansion.

    Structural design for pressure-and temperature-resistant buildings
    (2019-01-01)

    Loads from explosions differ from seismic and wind loads due to their greater severity, continuity, rapidity, and thermal extremity. That is, explosions cause massive structural damage by exposing surrounding structures to extremely high pressure and temperature. Thus, structures at risk of explosive damage must be stronger than typical buildings in withstanding both ordinary loads and the additional pressure and temperature loads caused. Explosion-resistant structures are required in the petrochemical industry, explosive armories, power stations, and gas storage facilities, among others. This study aims to examine the structural performance of a building subject to three types of loads: (1) the pressure of 300 bars, (2) the temperature of 300 °C, and (3) the pressure of 300 bars combined with the temperature of 300 °C. The research analyzes three primary reinforced structures, namely columns, beams, and slabs, in terms of the parameters resulting from each scenario to determine a set of criteria for designing the structural components of explosion-resistant buildings.

    Comparative structural design for pressure-and temperature-resistant buildings with loads affecting externally on structures of different heights
    (2019-01-01)

    Loads from explosions can be classified as internal blast load and external blast load and these loads have great severity, continuity and rapidity. That is, explosions cause massive structural damage by exposing surrounding structures to extremely high pressure and temperature. Thus, structures at risk of explosive damage must be stronger than typical buildings in withstanding both ordinary loads and the additional pressure and temperature loads caused. Explosion-resistant structures are required in the petrochemical industry, explosive armories, power stations, and gas storage facilities, among others. This study aims to examine and compare the structural performance of two building of different heights, which are 5-floor and 2-floor, subject to three types of loads: (1) the pressure of 300 bars, (2) the temperature of 300 °C, and (3) the pressure of 300 bars combined with the temperature of 300 °C. The research analyzes three primary reinforced structures, namely columns, beams, and slabs, in terms of the parameters resulting from each scenario to determine a set of criteria for designing the structural components of the buildings to resist the external blasts.
