This paper examines many aspects of structural auditing, including visual examination, non-destructive testing, core sample, and testing. It also emphasises various building repairs and retrofitting procedures that should be employed after a structural audit. As the structure matures, it need frequent maintenance and inspection in order to avoid further damage. The health and performance of a building are dependent on its maintenance quality. In order to protect the structure from environmental effects, it should be monitored on a regular basis by a professional. As a result, a structure audit is performed to assess the overall health of the building. A structure audit is a preliminary technical survey performed on a structure to recommend repair solutions.

LPG Storage Tank berkapasitas 50 Ton yang telah terinstalasi dan beroperasi sejak tahun 2010 akan dikaji kelayakan dan sisa umur pakai dari pressure vessel tersebut. Metode pengujian yang dipergunakan adalah Non-Destructive Testing (NDT) - Ultrasonic Testing (UT) pada bagian shell dan head untuk mendapatkan nilai actual thickness dari pressure vessel serta dilakukan Visual Examination. Nilai thickness tersebut dipergunakan untuk menganalisis dan mengkalkulasi thickness required (Treq), nilai Corrosion Rate (CR), Maximum Allowable Working Pressure (MAWP) serta umur sisa (Remaining Life) dari LPG Storage Tank tersebut. Dari hasil analisa serta perhitungan maka didapat umur sisa pakai dari LPG Storage Tank kapasitas 50 Ton adalah 18 tahun dengan nilai laju korosi sebesar 0,043 mm/thn

Using the flexural vibration method of Fast Fourier Transform (FFT) non-destructive testing, the dynamic MOE of glass fiber reinforced soybean straw particleboard has been determined. The regression analysis among the dynamic MOE, the static MOE and MOR has been done, the significant correlation exists among the three values. And the prediction model has been built, the dynamic MOE can be used to realize the quality assessment by using the model. Using glass fiber to reinforce the soybean straw particleboard, the structure forms and positions of glass fiber have different effects on particleboard performance.

A computer model and the results of a numerical experiment for a sensitive element on a planar mushroom-shaped metamaterial with cells of the “Maltese cross” type are presented. The proposed electrodynamic structure is shown to be applicable for nondestructive testing of geometric and electrophysical parameters of technological media, as well as searching for inhomogeneities in them. Resonant frequency shift and change of the attenuation coefficient value of the structure serve as informative parameters.

A powerful non-destructive testing (NDT) technique is adopted to study the internal defects and elemental distribution/homogeneity and porosity of aerated brick and EPS aggregate poly brick samples. In the present study the internal defects like homogeneity, porosity, elemental distribution, EPS aggregate and aerator distributor in the test samples have been observed by the measurement of gray value/optical density of the neutron radiographic images of these samples. From this measurement it is found that the neutron intensity/optical density variation with the pixel distance of the AOI of the NR images in both expanded polystyrene (EPS) aggregate poly brick and aerated brick samples comply almost same in nature with respect to the whole AOI but individually each AOI shows different nature from one AOI to another and it confirms that the elemental distribution within a AOI is almost homogeneous. Finally it was concluded that homogeneity, elemental distribution in the EPS aggregate poly brick sample is better than that of the aerated brick sample.
