Ground-borne noise and vibration measurement of Bangkok Red line (Bang Sue-Rangsit)
Vibration transmission from production line to microelectronic-inspection equipment
Vibration transmission from production line to the microelectronics inspection & measurement equipment
Measurement of pile-driving induced ground vibration for sensitive machine functionality and accuracy
Effect of pile-driving induced ground vibration to sensitive machines operation
Load testing and Analysis of 3000-ton wheat silo
Determination of silo load path, load distribution and new parameters for design and construction of new silos
Factory floor load test for heavy warehouse use
A factory floor was first investigated to verify whether the floor slab is on pile or on ground. Then the load test was conducted to justify the load carrying capacity. Oil barrels were used as load application and placed on the test are by forklifts. Load magnitude per agreement was taken to be equivalent […]
Anchor bolt pullout/Shear tests
Several types and different configurations of anchor bolts were tested for pullout and shear. First of all, M24 and M27 bolts used to support 3 advertisement boards with dimension of 12 m long and 5.65 m height each were tested under both pullout and shear. The pullout and shear loads were measured and plotted against […]
Water permeability and concrete carbonation test
The existing condition and the remaining life lasting of the water storage structure were evaluated using water permeability test and concrete carbonation test
Sensitive machine vibration measurement and vibration isolation problem
A 6-ton MRI Scanning machine was planned to place on the 1st floor of a Tower. To fulfill the specifications of the MRI installation, the existing vibration condition of the floor had been checked since vibration on floor will lead to the distorted images and affect the image quality from scanning. RE conducted the floor […]
Microelectronics fabrication facilities vibration measurement
2 buildings consisting of a 5-story building and a 2-story building were installed with sensitive machines, which fabricate the microelectronics components such as external hard drives. Those require a free-vibration condition. Thus, 70 locations of machine vibration were measured. In each location, vibration in all three axes including two horizontal directions (X, Y) and one […]
