“…Figure 8 shows the variation in support reactions with respect to the applied load; the relationship between applied loads and support reactions predicted by linear two‐dimensional (2‐D) finite element (FE) analysis 19 is also plotted. The analysis of support reactions was limited to the panel‐to‐beam joint because the support reaction was measured only in the panel‐to‐beam joint using a load cell.…”

“…The structural safety of the developed panel‐to‐base joint technique (joint reinforcing bar and L‐shaped steel plate) was verified from the comparison of experiments with cracking and nominal moment capacities calculated using the equations specified in ACI 318‐19 17 and with the requirements of four seismic connection performance specified in NEHRP 18 . To consider the support constraint conditions, the maximum flexural moment was calculated using a collapse mechanism 19 according to fixed or hinged ends of the panel‐to‐base joint. In addition, the ductility of PLC insulation panels was investigated using the displacement ductility ratio and work damage index.…”

This study investigated the structural safety of the developed panel‐to‐base joint technique for full‐size precast lightweight aggregate concrete (PLC) insulation panels subjected to cyclic lateral loads. The main parameters were the compressive strength of insulating concrete and the safety factor of the joint reinforcing bar for connecting with the base or beam. The test results revealed that the PLC insulation panel specimens with a safety factor of 1.0 experienced severe pinching effect and low ductile performance. However, the PLC insulation panel specimens with a safety factor of 1.6 exhibited higher flexural moment capacity, displacement ductility ratio, and work damage index than those with a safety factor of 1.0. Consequently, the overall flexural behavior of the PLC insulation panel specimens with a safety factor of 1.6 can be developed stably, resulting in satisfactory seismic connection performance requirements specified in NEHRP. Meanwhile, the developed panel‐to‐base joint using the joint reinforcing bar and L‐shaped steel plates can be considered as a fixed end according to the analysis of the collapse mechanism, as with spliced sleeve or welding plate joints.

The purpose of this study is to analyze the deflection of the prestressed beams. In this paper, a finite element model for deflections of prestressed beams is presented. Proposed finite element model was verified comparing with existing experimental results, and it showed a good agreement with the experimental results. Also, a parametric study has been conducted to analyze the influence of eccentricity, span-depth ratio, and prestressing force. The finite element model results were compared with hand calculation results. Deflections were increased as the eccentricity decreases, the span-depth ratio increases, and the prestressing force decreases. Hand calculation overestimated the deflection when the eccectricity or prestressing force is too small.
