This study introduces an anlytical model for estimating shear strengths of reinforced concrete (RC) members with corroded tensile reinforcing bars. The bond strength model for corroded reinforcing bars developed in the previous study was extended for shear analysis. A force equilibrium condition between adjacent cracks was established considering the bond mechanism of reinforcing bars, through which the shear contributions of aggregate interlock in cracked tension zone and uncracked concrete in compression zone were quatitatively determined. In addition, a bond failure criterion was introduced in the shear analysis model, such that bond failure owing to insufficient bond strength caused by corrosion can be reflected. The proposed model was verified in detail through comprehensive comparison with existing shear test results of corroded RC beams. Consequently, it appeared that the proposed model closely captured the change in shear capacity with respect to the degree of corrosion with a good accuracy.

The growing demand for energy-efficient buildings and diverse façade designs has increased thermal bridging at slab– balcony connections due to insulation discontinuity. Thermal break systems at these connections must ensure both thermal performance and structural stability. This study investigates a post-attached balcony thermal break system based on a precast concrete (PC) construction method through flexural and shear experiments, supported by finite element analysis using LS-DYNA. The results confirm stable structural behavior under both flexural and shear loading conditions and the numerical models successfully reproduce the observed damage mechanisms. The findings provide a basis for the structural evaluation and design of post-installed balcony thermal break systems.

Fixed parameters in metaheuristics like Differential evolution (DE) limit truss optimization efficiency. This study proposes a PS-QDE(Phased strategy Q-Learning DE) algorithm that uses Q-learning to dynamically adapt parameters. A novel "Strategy switching factor" is also introduced to adjust the exploration-exploitation balance based on convergence. The PS-QDE algorithm was validated on four truss optimization problems (10-bar to 200-bar) with frequency constraints. Results show PS-QDE provides more stable convergence and superior or competitive optimal solutions compared to standard DE.

The optimal design of steel plate girders has traditionally relied on meta-heuristic techniques, such as Genetic Algorithms (GA), to handle discrete design variables and complex non-linear constraints, including shear buckling and section classification. However, these methods suffer from high computational costs as they require repetitive re-optimization for every new load condition. To address this limitation, this study proposes a highly efficient Sequential Multi-Agent Reinforcement Learning (MARL) framework based on the Agent-Environment Cycle (AEC) architecture. Unlike parallel one-shot approaches, the proposed model effectively learns the dependencies between design variables by determining them sequentially. Furthermore, to maximize cost efficiency during the inference phase, we introduce an Adaptive Inference Chain combined with a deterministic DCR-based Shrink-Refine algorithm. Experimental results on 100 diverse load cases demonstrate that the proposed method achieves an average cost reduction of 8.2% compared to the GA baseline while maintaining 100% feasibility. With an inference time reduced to approximately 76 ms, the model demonstrates significant potential for real-time automated design. Additionally, an in-depth analysis of cases where the Demand-Capacity Ratio (DCR) fell short of the target clarifies the exploration limits within the discrete design space and validates the robustness of the algorithm.

Glass Fiber Reinforced Polymer (GFRP) shear connectors used in Insulated Concrete Sandwich Wall Panels (ICSWPs) have traditionally been evaluated for composite action based on global stiffness and strength. However, such approaches are limited in capturing local interface behavior and variations in composite action. This study proposes a strain-based shear-flow evaluation method to reflect the local structural behavior of ICSWPs. Theoretical shear flow was analyzed using flexural strain distributions obtained from existing experimental studies. Review of experimental data revealed that composite action decreases under repeated loading due to damage to GFRP shear connectors and interfaces, and that shear flow exhibits nonlinear behavior that is not proportional to the degree of composite action. To evaluate shear flow theoretically, curvature and neutral axis (NA) location were determined from strain distributions using three analytical approaches. Results showed that shear flow was maximized in partial composite action and decreased as composite action increased, with a sharp increase at low composite levels. The proposed approach highlights the importance of considering nonlinear interface shear flow for accurate evaluation of composite action in ICSWPs.

This study presents a field application framework for remote safety monitoring of buildings during demolition using Total Station measurements and prism targets. A large-scale demolition site consisting of two blocks and eight buildings was selected, and five buildings with stable line-of-sight were monitored. Target prisms installed at designated floors were repeatedly observed to obtain vertical-transverse (VT) displacement components, from which building tilt (VT-corrected) and interstory drift ratios were derived as primary safety indices. To address high-frequency fluctuations caused by construction stage changes and measurement conditions, representative values were summarized for long-term trend interpretation. The maximum VT-corrected tilt was 0.00199 (B203) and 0.00197 (B101), indicating that all monitored buildings remained within the reference level of 1/500. The maximum interstory drift ratio was 0.00586 (B101), which remained below the comparison criterion of 0.010 adopted for monitoring. In addition, the maximum VT displacement at the lowest installed prism reached 0.04422 m (B202), approaching but not exceeding the comparison criterion of 0.045 m. No monotonic accumulation toward a single direction was identified over the monitoring period. The results demonstrate that Total Station based remote monitoring can provide quantitative, stage-by-stage safety information during demolition under constrained site access conditions.

This study evaluated the removal performance of wall drainage panels incorporating porous-material kits for air pollutants and PM2.5 particles. Laboratory and parking lot mock-up tests demonstrated that three coconut shell powder kits for NOX removal and two zeolite bead kits for SOX removal provided the highest efficiency. Both materials maintained stable NOX and SOX removal rates over a nine-month exposure period, and PM2.5 particle removal performance also remained consistent. These results confirm that the proposed system can effectively mitigate both gaseous and particulate pollutants as a practical air quality improvement technology. However, further long-term evaluation exceeding one year is required to verify the stability of its removal performance.
