钢筋混凝土剪力墙（RCSW）占主导地位的建筑物，采用特殊的隧道形式技术建造，通常在克罗地亚共和国建造。振动的基本周期在预测结构在动力激励下的预期行为中起着重要作用。抗震规范中已有基本周期的经验计算公式，主要取决于建筑物的高度、材料（钢、钢筋混凝土）和结构体系类型（框架、剪力墙等）。这些公式通常是通过对实测的既有建筑物在地震作用下的基本周期进行回归分析，由经验数据导出的。本文的主要目的是比较一个真实的钢筋混凝土建筑的数值分析获得的基本周期使用一个特殊的隧道形式的技术与使用不同的建筑规范中的公式获得的周期。
Reinforced concrete shear wall (RCSW) dominant buildings, constructed using a special tunnel-form technique, are commonly built in the Republic of Croatia. The fundamental period of vibration plays a major role in predicting the expected behavior of structures under dynamic excitations. Empirical formulas for the estimation of the fundamental period have been included in seismic codes, which mainly depend on building height, material (steel, reinforced concrete (RC)) and structural systems type (frame, shear wall, etc.). These formulas have been usually derived from empirical data through regression analysis of the measured fundamental period of existing buildings subjected to seismic actions. The main purpose of this paper is to compare the fundamental period obtained from numerical analysis of a real RC building constructed using a special tunnel-form technique with the periods obtained using formulas in different building codes.
