“…Non-destructive and micro-destructive testing methods for estimating the compressive strength of concrete have been studied extensively, and many methods have been put into practical use and standardized. The most commonly used NDT methods are a rebound hammer test [4][5][6][7] and ultrasonic pulse velocity [8][9][10][11][12][13][14]. A combination of those methods [15][16][17] is also widely used to evaluate the existing concrete structures.…”

Non-destructive testing has many advantages, such as the ability to obtain a large number of data without destroying existing structures. However, the reliability of the estimation accuracy and the limited range of applicable targets remains an issue. This study proposes to a novel pin penetration test method to determine the early age compressive strength of concrete before demolding. The timing of demolding and initial curing are determined according to the strength development of concrete. Therefore, it is important to determine the compressive strength at the early age before demolding at the actual construction site. The applicability of this strength estimation methodology at actual construction is investigated. Small test holes (12 mm in diameter) are prepared on the mold surface in real construction sites and mock-up specimens in advance. The pin is penetrated into these test holes to obtain the relationship between the compressive strength and the penetration depth. As a result, it is confirmed that the pin penetration test method is suitable to measure the early age compressive strength at actual construction site. This allows the benchmark values for compressive strength, necessary to avoid early frost damage, to be directly verified on the concrete structural members at the construction site. For instance, the compressive strengths of greater than 5 MPa and 10 MPa can be confirmed by the penetration depths benchmark values of 8.0 mm and 6.7mm or less, respectively.

“…To assess the extent of the damage caused by the fire, researchers can examine the post-fire mechanical properties of the reinforced concrete elements [6][7][8]. These properties include compressive strength, tensile strength, and modulus of elasticity, which can provide valuable information on the assessment of the post-fire performance of the building.…”

On September 21, 2020, the Pasar Wage Building of Kabupaten Banyumas was hit by a fire causing spalling of the concrete and thus exposing the steel reinforcement. This damage can affect the performance and safety of the building. For this reason, an evaluation is needed to determine the performance of the post-fire structure to propose the necessary repair and retrofitting. Investigation and testing in the field were carried out in this study as primary data for seismic performance analysis. Static pushover analysis was carried out to provide information about the structure's collapse performance using damage states of the FEMA P-58 criteria. The seismic performance was then presented with a fragility curve to illustrate the probability of building damage. The results show that the maximum base shear value is 3033 kN with a displacement of 0.063 m. At a target displacement of 0.027 m, the base shear is 2618 kN. The probability of structural damage within a category of extensive is 77% if an earthquake at the Design Basic Eartquake (DBE) level strike the building. The probability of structural damage becomes 50% extensive and 50% complete at the Maximum Considered Earthquake (MCE) level.
