Three Dimensional Finite Element

Human population is growing around the world day by day, necessitating highly sustainable and energy efficient building systems. In conventional building systems, significant amount of energy is consumed for providing thermal comfort to the occupants. Materials used for thermal insulation not only increase the cost of the buildings but also increase the dead weight. Structural concrete insulated panel system (SCIP) provide thermally efficient, light weight, and low-cost solution as compared to the conventional systems. SCIP system is new innovation in which, insulation material is placed between two layers of concrete. Due to low weight, it can be easily handled and transported to project sites. In present research, the performance of SCIP walls in a typical school double story building is examined by three-dimensional finite element analysis, using SAP2000. The response is evaluated by varying the thickness of the insulation layer in terms of safety and serviceability. The results show that the buildings incorporating SCIPs are capable to withstand high dynamic and earthquake loads and are significantly economical as compared to the conventional building systems.

Waterstops are commonly used at cold joints in construction of liquid containing concrete structures. A common issue with application of waterstops, is their conflict with top layer of slab reinforcements. A common solution is to form an upturn part that raises the waterstop clear of the top slab bars. However, effects of these different types of construction joints on the performance of structures have not been investigated. To that end, full-scale wall-slab specimens, each representing a different type of construction joint, are built and tested under different monotonic and cyclic loadings. The performance of these specimens is compared with regards to first cracking, limit state capacity and leakage. Results of the tests show that conventional flat joint, behaves more rigidly compared to other types of joints. A non-linear finite element analysis of a typical wall-slab specimen, is also presented and its results are compared with the results of the experiments.
