Beam-to-column joints are one of the most common types in metal structures. In design load-bearing aluminium structures, welding, as a joining method, is often avoided because localised degradation mechanical properties heat-affected zone (HAZ). However, recent experimental studies on extent and strength HAZ show significant difference compared to very conservative rules when modern welding tec...

Beam-column joints constructed in the pre-seismic building code do not provide transverse reinforcement and good detailing within region. These cause occurrence of brittle shear failure, which is one factors affecting number reinforced concrete (RC) moment resistance structures collapsing during an earthquake. Therefore, this study a beam-column joint with non-seismic was designed strengthened ...

Column strengthening is a very common practice for improving the seismic performance of reinforced concrete frame structures or repairing damage after event. Several methods are employed column strengthening, which can improve strength by preventing its shear, bending compression failure. However, not all allow connections between adjacent floors, thus beam-column joint could be limited column-...

In the present study, an experimental and theoretical investigation is carried out on reinforced concrete exterior beam-column joints strengthened with hybrid fibre polymer (HFRP). The effect of reversible distress that develops in joint region due to seismic force determined experimentally by applying reverse cyclic loading tip beam. analysis, shear strength was determined, satisfactory correl...

This study presents the optimal drift design method to control the elastic and inelastic performance of steel moment frames. This is formulated as a problem that minimizes the lateral displacement at the top of a building satisfying the constraints on the total structural weight and the column-to-beam strength ratios at the joints. This uses the resizing method based on the linear static analys...

To optimize the seismic performance in high-rise buildings, changes of beam-column joints steel structures buildings when they are impacted analyzed to obtain optimal choice joint combination. The most commonly used beam and column selected as research objects. Firstly, finite element model shell force established then combination six kinds is established. Secondly, applied data common impact a...

Precast concrete structure is a low-carbon building system that has been attracting extensive attention in recent decades. Beam–column joints are the weak links precast structures. Past studies showed five-spiral stirrups had excellent confinement effects and potential to enhance seismic performance of This study proposed reinforcement beam–column by using investigated their performance. Consid...

The finite element method (FEM) can be applied to practically analyze the tall buildings in which the shear walls are used to resist the lateral loads. Accordingly, a variety of displacement and strain-based as well as frame macro elements have been proposed for analysis of the tall buildings. With respect to application of the lower order plane stress elements, analytical problems may arise wi...

This paper presents a simple displacement-based seismic design method for RC frames with steel damper column. As numerical example, two 10-story frame building models are shown. The results of nonlinear time-history analysis show that the peak displacement at equivalent height is close to target displacement. strength demand beam ends connected columns, and beam-damper column joints, calculated...
