The magnitude of the earthquake load received by the structure is influenced by the peak acceleration parameters of the bedrock for a period of 0.2 seconds (Ss) and a period of 1 second (S1). This research measures the effect of increasing Ss by 0.1g on 10 and 30 storey building structures in DIY. The parameters measured include frequency, story drift, p-delta influence, stiffness and stability index in 7 sub-districts in DIY using equivalent static earthquake analysis and response spectrum variance analysis. The frequency of 10 and 30 storey buildings in the first 3 modes is less than 1 Hz. This frequency is below the peak acceleration frequency of the DIY earthquake which was measured in the range of 1.25 Hz to 7.14 Hz in the 7 sub-districts studied. The frequency of earthquake vibrations in DIY is more dangerous for low to medium storey buildings or buildings with a period (T) of less than 0.8 seconds. An increase in Ss of 0.1g in a 10-story building resulted in the earthquake force distribution increasing by 3.99% in the x and y directions, story drift increasing by 4.12% in the x and y directions, p-delta increasing by 0.46% in the x and 0.28% in y direction, rigid structure, each floor is a swaying portal. Meanwhile, in a 30-story building, the earthquake force distribution increased by 6.24% in the x and y directions, story drift increased by 6.27% in the x direction and 5.31% in the y direction, p-delta increased by 0.15% in the x direction and 0.55% in y direction, rigid structure, each floor is a swaying portal..
结构所承受的地震荷载大小受 0.2 秒周期（Ss）和 1 秒周期（S1）的基岩峰值加速度参数的影响。本研究测量了将 Ss 增加 0.1g 对 DIY 中 10 层和 30 层建筑结构的影响。采用等效静力地震分析和反应谱方差分析，测量了 DIY 7 个分区的频率、楼层漂移、p-delta 影响、刚度和稳定指数等参数。10 层和 30 层建筑的前 3 个模态频率小于 1 赫兹。这一频率低于 DIY 地震的峰值加速度频率，在所研究的 7 个分区中，峰值加速度频率的测量范围为 1.25 赫兹至 7.14 赫兹。DIY 地震的振动频率对中低层建筑或周期（T）小于 0.8 秒的建筑更危险。在刚性结构中，每层楼都是一个摇摆门，当 10 层楼的 Ss 增加 0.1g 时，地震力分布在 x 和 y 方向上增加 3.99%，楼层漂移在 x 和 y 方向上增加 4.12%，p-delta 在 x 方向上增加 0.46%，在 y 方向上增加 0.28%。同时，在一栋 30 层的建筑中，地震力分布在 x 和 y 方向上增加了 6.24%，楼层漂移在 x 方向上增加了 6.27%，在 y 方向上增加了 5.31%，p-delta 在 x 方向上增加了 0.15%，在 y 方向上增加了 0.55%，刚性结构，每层都是摇摆门户。
