The Structure of Reinforced concrete building using kalsi floor plate is one alternative for reduced the weight of the building structure. The floor plate usually used conventional concrete, can be replaced with kalsi floor 20. The aim of the research is to analysis of the behavior of reinforced concrete building using conventional concrete slabs and kalsi floor 20. The building structure as the model in this research is the building structure of four floors and was designed to follow the rules of SNI 2847: 2013. Evaluation of seismic behavior in accordance with the SNI 1726: 2012 was conducted out by applying pushover analysis using SAP 2000 software. The analysis results showed that drift ratio of plates floor structure models smaller than the kalsi floor plate structure. The pushover analysis results show the level of performance of all structural models according to FEMA-356 / ATC-40 able to provide nonlinear behavior which is indicated by the initial phase of the majority of plastic joints on beam elements and beam sway mechanism. The performance level of the structure with conventional concrete slab includes at immediate occupancy level, while the performance level of the structure with with kalsi floor plate includes at life safety level.

A multi-storey reinforced concrete building is very prone to collapse. Therefore, proper structural planning is needed in order to qualify the strength and security of the structure. Fajar Biru Building is a building that will be built in Karangsuko village of Trenggalek Regency, East Java. The building functioned as a cost with a building area of 340 m2, and has a total of 4 floors. The method used is the SRPMM (Medium Moment Musician Frame System) method which refers to SNI 1726:2012, and SNI 2847:2013. Planning includes the calculation of beams, floor plates, and columns. From the results of the calculations that have been done. on the floor plate structure with a plate thickness of 120 mm, Ø12 tree bones are used with a distance of 100 mm for pedestals and 150 mm for field areas. On the looping of B1 beams with dimensions of 300x350 mm used 6-D16 tree bones for focus and 4-D16 for field areas with Ø10-70 mm for focus and Ø10-140 mm for field areas. For the repeating of Column K1 with dimensions of 300x600 mm used 10-D16 principal bones with a Ø10-70 mm dimension. So that from these results can be used as a reference in the implementation of the construction of the blue dawn building.

In this article, the applicability of mode-adaptive bidirectional pushover analysis (MABPA) to base-isolated irregular buildings was evaluated. The point of the updated MABPA is that the peaks of the first and second modal responses are predicted considering the energy balance during a half cycle of the structural response. In the numerical examples, the main building of the former Uto City Hall, which was severely damaged in the 2016 Kumamoto earthquake, was investigated as a case study for the retrofitting of an irregular reinforced concrete building using the base-isolation technique. The comparisons between the predicted peak response by MABPA and nonlinear time-history analysis results showed that the peak relative displacement can be properly predicted by MABPA. The results also showed that the performance of the retrofitted building models was satisfactory for the ground motion considered in this study, including the recorded motions in the 2016 Kumamoto earthquake.

This study covers the application of Static and Dynamic nonlinear analysis to an old moment-frame reinforced concrete building. The case study selected is a template one designed in 1982 without shear walls and built throughout Albanian region in the communism era using old standards (KTP 2-78). For the capacity calculation, Pushover analysis is performed using an inverse triangular load pattern. The demand calculation is conducted using Incremental Dynamic Analysis (IDA) as a method which provides the response behavior of the structure from the elastic range until collapse. For the dynamic analysis is used a set of 18 earthquakes with no marks of directivity. Limit states are defined for both Pushover and IDA based on the FEMA 356 guidelines. The mathematical model is prepared in the environment of Zeus-NL, a software developed especially for earthquake applications. The parameters defined for the IDA analysis are 5% damped first mode spectral acceleration (Sa(T1,5%)) for the intensity measure (IM) and maximum global drift ratio (ϴmax) for the damage measure (DM). In addition, limit states are selected for the pushover curve as Immediate Occupancy (IO), Life Safety (LS) and Collapse Prevention (CP). Similarly, for the IDA curve the limit states are selected as IO, CP and Global Instability (GI) based on FEMA guidelines. Furthermore, IDA curves are summarized into 16%, 50% and 84% fractiles as suggested in the literature. Additionally, a comparison between Pushover and IDA median (50% fractile) is shown from the same graph to illustrate the correlations between performance levels. Finally, structural performance is interpreted based on the outcomes.
