Prediction of Lightweight Aggregate Concrete Compressive Strength
Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the main methods of non-destructive testing in the assessment of compressive strength...
متن کاملNon-destructive evaluation of the spatial variability of reinforced concrete structures
Spatial variability of concrete is an important characteristic, which qualifies the non-homogeneity of concrete properties within structural components. Assessing it can be of great interest for damaged areas localization and for reliability analysis of structures. A two-stage experimental program was carried out using non-destructive testing (NDT) on laboratory concrete slabs in outdoor enviro...
متن کاملDeveloping a Feature Extraction of Existing Structures Using an Ambient Vibration Test
The paper aims to extract the dynamic properties of existing structures without utilizing the analytical models. The ambient vibration testing could be used on any type of frame such as concrete, steel and masonry to investigate the structural vulnerability. The method could be the first stage and necessarily for the retrofit process. To achieve this aim, the ambient vibration testing can...
متن کاملTransmission Approach for Near-Field Non Destructive Characterization of Steel Fiber Reincorced Concrete at Microwave Frequencies
Steel Fiber-Reinforcement is a way to strengthen concrete structures which results to be more flexible and less expensive than the conventional hand-tied rebars, while still increasing the tensile strength. In order to ensure the prescribed tensile strength, the conglomerate needs to have a certain volumetric density of fibers uniformily distributed over the structure. In this paper, a novel st...
متن کاملIdentification of Delamination Damages in Concrete Structures Using Impact Response of Delaminated Concrete Section
The deteriorating national infrastructures demand improved non-destructive evaluation (NDE) methods for detection of defects which reduce the integrity of the structures. Vibration resonance tests offer an efficient NDE method to identify and characterize shallow (near surface) delamination defects in reinforced concrete slabs In this study, we compare the capability to visualize near surface d...
