Chemical anchor pull out testing

RE conducted the Chemical Anchor Pull Out Test. This chemical anchor was installed on the floor as moment-resisting support of the new column. Thus, this chemical anchor must be able to resist tension force according to the design. In this case, proof load according to the design was applied. Test frames, load cells, displacement transducers, and the data acquisition system were used.

Pull-off test

The Concrete Pull-Off Test is used to determine the direct tensile strength of a concrete or the bond strength of concrete mixture. The testing equipment consists of metal test circular plates, threaded rods, epoxy, a core drill, a load cell, a displacement transducer, and a hydraulic jack.

Post tensioning Slab Load Testing

A building under construction experienced cracks on its post-tensioned slab. The structural capacity was questionable for a designed live load of 400 kg/m2 and a super imposed dead load of 250 kg/m2. Thus, a load test was conducted to determine the actual floor capacity.

Slab on ground Load Testing

RE conducted a load test on a ground slab in a factory on Suksawat road, Samut Prakan. In the design point of view, a ground slab is normally designed using the linear spring distribution support assumption. However, in reality, a ground slab often experiences nonlinear behavior. The slab on ground load test project was deemed necessary when there was a plan for new production line machines to be installed.

Steel Tensile Test

The Steel Tensile Test is used to determine yield strength, ultimate strength, and fracture strength of existing steel members. In the testing process, samples are taken from the steel members in structures such as factory roof trusses or parking roof trusses. The results of the Steel Tensile Test will be used in further analyses and evaluations of the structures.

Pile location detection

One very common problem is that the drawing or evidence of the floor pile layout or location is missing. As a result, a thorough floor capacity analysis cannot be done. Load carrying capacity also cannot be verified. When dealing with one of these cases, RE team conducted the Non-Destructive Pile Detection on the concrete floor of a factory in the Bangpa-In Industrial Estate.
