Abstract

Jammed occurs due to the road infrastructure services level which is smaller than traffic movement needs that available. And the road which potentially to congest is ZA Pagar Alam street. So the government had made a solution to decrease the traffic jam by built an underpass on ZA Pagar Alam street. Furthermore, considering the need for underpass construction aims to reduce jam that occurs, so the writer bring out a research topic that is analyzing traffic flow after the underpass was built and comparing with the traffic flow before the underpass was built. The analysis of this road section performance using the 2014 Indonesian Road Capacity Guidelines method.It is known that the degree of saturation has decreased from 2013 by 1.00. It became 0.655 in 2016 and still dropped in 2019 to 0.63. But, from 2016 to 2019 the decrease was not significant. The speed in 2016 was 42.1 km / hour, and in 2019 was 41 km / hour. From the speed data, the results are not appropriate to RSNI T-14 2004 whereas the speed standard for urban roads should be 50-80 km / hour. So, it can be concluded from the comparison research of before and after the underpass was built, the construction of underpass on the section of ZA Pagar Alam street is not effective to decrease traffic jam.Keywords: Road Section, Degree of Saturation, Underpass

Pushover analysis is one of the methods used to analyze earthquake loads in order to determine the structural collapse behavior of earthquake loads. The purpose of this study is to determine and analyze the level of structural performance, the maximum base shear force held by the structure, the collapse pattern and the level of structural ductility due to earthquake loads. Based on the analysis results, the target displacement value obtained by the FEMA-356 was 251.6mm for the x-axis and 210.6mm for the y-axis while the ATC-40 obtained a value of 322.027mm for the x-axis and 229.491mm for the y-axis The level of performance produced by the two methods was damage control where the risk of human casualties was very small, the damage that occurs can still be repaired and the building is still able to withstand the burden of the designed earthquake. The structure collapse mechanism has strong column weak beam mechanism so that the structure of the building is relatively safe during the earthquake load. The ductility level of building based on SNI 1726:2002 was a partial ductile with the actual reduction factor, R was 4.07. Keywords: pushover analysis, damage control, ductility. AbstrakRumah sakit merupakan salah satu fasilitas yang termasuk bangunan penting kategori IV sehingga dibutuhkan perencanaan struktur tahan gempa dimana bangunan harus tetap berdiri setelah diberikan beban gempa rencana.
