In order to address the performance complexity of the various constituent materials of (dense-column) latticed concrete-gypsum composite panels and the difficulty in the determination of the various elastic constants, this paper presented a detailed structural analysis of the (dense-column) latticed concrete-gypsum composite panel and proposed a feasible technical solution to simplified calculation. In conformity with mechanical rules, a typical panel element was selected and divided into two homogenous composite sub-elements and a secondary homogenous element, respectively for solution, thus establishing an equivalence of the composite panel to a simple homogenous panel and obtaining the effective formulas for calculating the various elastic constants. Finally, the calculation results and the experimental results were compared, which revealed that the calculation method was correct and reliable and could meet the calculation needs of practical engineering and provide a theoretical basis for simplified calculation for studies on composite panel elements and structures as well as a reference for calculations of other panels.

In recent years, concrete has become a widely used material for general purposes in the structural area due to its excellent performance and properties. Hence, an increasing number of concrete structures are built, and a huge amount of building stock has been occurred around the world. However, because of the many progress (i.e., natural disasters), some of the concrete structures are demolished and their status is changed into rubble, and hence this becomes an environmental problem threatening the nature. To struggle with the rubbles, -a brilliant idea -recycling concrete is appeared and to disposal the rubbles in concrete works become a subject in the authorities' agenda. Also, according to the brilliant approach, the studies focus on some experiments and simulation works (i.e., finite element modeling) to analyze the use of rubbles as recycled aggregate (RA) in concrete, recycled aggregate concrete (RAC) and reinforced RAC (RRAC) properties. At this point when a deep look is concentrated on the papers on RAC and RRAC, the reviews generally include experimental works of the research but rarely or hardly ever consider the simulation stages of the researche. Hence, this paper is drawn as a state-of-the-art report on modeling works of RAC and RRAC. Also, this paper gives finite element model (FEM) details of the examined research to improve the future studies on RAC and RRAC with helpful comments and directions.Cite this article as: Dilbas H.

“…∆ y in Equation (23) is obtained by the equivalent yield point determined on the skeleton curve. The “equivalent energy method” [ 41 ] is used to define an equivalent yielding point. The ultimate displacement ∆ u in Equation (23) is obtained from the descending section of the skeleton curve where the bearing capacity is reduced to 85% of the maximum value.…”

The dynamic behavior of a PPSRC beam–column joint is related to constraint effect, strength deterioration and strain rate effect. Then, it can be assessed by bearing capacity, stiffness degradation, displacement ductility and energy consumption. The results show that the increased strain rate causes growth in ring stiffness, bearing capacity and energy consumption of PPSRC beam–column joints. However, the influence of shear span-to-depth ratio on dynamic mechanical properties of PPSRC beam–column joints is more obvious than that of strain rate. Regardless of strain rate, the bearing capacity, initial stiffness, ring stiffness and energy consumption of PPSRC beam–column joints decrease as the shear span-to-depth ratio increases. Moreover, the ring stiffness under reverse direction is smaller than that the under forward direction at each displacement level. However, the stiffness degradation under a lower shear span-to-depth ratio is more obvious than that under a higher shear span-to-depth ratio. Moreover, the displacement ductility with a higher shear span-to-depth ratio is better than that with a lower shear span-to-depth ratio. Finally, the mechanical properties of PPSRC beam–column joints are affected by the extension length of partial steel plate, and the reasonable extension length of the partial steel plate in the column is affected by the shear span-to-depth ratio.
