Abstract

Introduction: The roof truss construction used in the cultural heritage building in this analysis is a truss roof truss with 2L angle steel profiles (double elbow) 40.40, 50.50, 60.60, 70.70, IWF steel profile gording 150x150, and roof tile coverings, with a length ofroof 102 m, width 21.6 m, height 5 m, with a distance of 7.4 m and 4.1 m truss. The cultural heritage building discussed in this analysis is the roof, namely the horses. Method: The method used in this study is to collect data in the form of shop drawings. The purpose of the study was to identify the capability of the roof structure with the updated loading regulations RSNI 1727-2018. Results: This analysis uses the latest RSNI 1727-2018 loading regulations and the latest SNI 1729-2015 steel regulations, does not change the installed materials and existing shapes, and does not use earthquake and rain loads, only live/maintenance loads, heavy dead loads. roof coverings, ceilings and hangers, and compressed and suction wind loads. Conclusion: From the resultsof this analysis, it is assumed that the rusted steel profile has been replaced, there are two truss rods that need to be replaced with a 2L 80.80 double angled profile with initial data of a 70.70 2L profile. Analysis of the 3-dimensional roof structure with SAP2000 software by reviewing the dead load, the live load of workers according to the loading regulations of the RSNI 1727-2018, taking into account the compressed wind load of 75.82 m2, the suction wind load of 57.37 m2 according to the wind speed of 40 m/s

1921年，用2000年SAP软件拆除了一座文物的钢屋顶框架

本分析中所采用的文化遗产建筑屋架结构为2L角钢型材(双弯头)40.40、50.50、60.60、70.70,IWF钢型材铆钉1500x150，屋面覆盖瓦的桁架屋架，屋架长102 m，宽21.6 m，高5 m，屋架间距7.4 m, 4.1 m。本次分析讨论的文化遗产建筑是屋顶，即马。方法:本研究采用的方法是以车间图纸的形式收集数据。该研究的目的是根据最新的加载法规RSNI 1727-2018确定屋顶结构的能力。结果:本分析采用最新的RSNI 1727-2018加载法规和最新的SNI 1729-2015钢材法规，不改变已安装材料和现有形状，不使用地震和雨荷载，仅使用活/维护荷载，重恒载。屋顶覆盖物、天花板和衣架，以及压缩和吸入风荷载。结论:从分析的结果来看，假设生锈的钢型材已经被替换，有两个桁架杆需要替换为2L 80.80双角型材，初始数据为70.70 2L型材。采用SAP2000软件对三维屋面结构进行分析，根据RSNI 1727-2018荷载规定，考虑压缩风荷载为75.82 m2，吸气风荷载为57.37 m2，风速为40 m/s
