Application of the BIM to Assess the Risk of conserved Buildings

Abstract

The purpose of this research is to assess the risk of conservation building structures. By using the building information modeling process, it helps to analyze the components of the building structure. Research begins with data collections by testing the compressive strength of concrete of columns, beams and slab. Then surveyed the cross-sectional dimensions of columns, beams, slabs, width, length and height of a 4-storey reinforced concrete building. And then developed into a 3D model with BIM software (Software BIM). The researcher has determined the tensile strength of the reinforcing steel is 2,400 kg/cm2 for the compressive strength of concrete is 160, 170, 180, 190, 200, 210, 220, 240 and 300 kg/cm2 into the BIM software. It was found that high risk building, because that the probability of the building (column) will be damaged is equal to 0.0984 at the compressive strength of concrete 150, 160 and 170 kg/cm2. Medium risk building, because that the probability of the building (slab) will be damaged is equal to 0.1633 at the compressive strength of concrete 150, 160 and 170 kg/cm2. Low risk building, because that the probability of the building (beam) will be damaged is equal to 0.0727 at the compressive strength of concrete 150, 160 and 170 kg/cm2. It shows that the building information modeling process can be well applied in building risk management.
