dc.description.abstract | 脈衝型地震動通常在斷層附近被觀察到,在速度歷時中具有一個或多個脈衝。這種地震動會對隔震系統產生嚴重的破壞和巨大的結構需求。使用額外的黏性阻尼器可能可以滿足大位移需求,但會將額外的力量傳遞到上部結構。然而,與受到非脈衝型地震動或脈衝型地震動的非線性歷時分析相比,目前很少有對於具附加黏性阻尼器之隔震系統的設計程序之有效性和準確性的研究或調查。 本論文全面評估了 (1) 目前 ASCE 7-16 和 AASHTO 2010 中規定的等效線性(EL) 方法以及沒用參數B 的等效線性方法用於設計受非脈衝型地震動或脈衝型地震動影響的具額外黏性阻尼器之鉛心橡膠隔震系統的準確性和有效性,(2) 阻尼器指數 (αd) 對結構反應的影響,以及 (3) 簡化方法的載重組合因子(CF1 和 CF2)對預測基礎剪力的效果。 本研究從PEER NGA West2 計畫和台灣國家地震工程研究中心的SSHAC 資料庫中收集了非脈衝型地震動和脈衝型地震動資料庫。非脈沖地震動選擇過程採用了一些標準,包括1)地震規模大於等於 6.5,2)工址至斷層破裂面最短距離小於20公里。此外,在兩個地震動數據庫的縮放過程中都採用了比例因子在0.25到4 之間的標準。 由三種 Qd、兩種 ξd 和三種 αd 組成的 21 個SDOF 模型用於執行 NRHA、EL和沒用參數B 的EL 方法。非線性歷時分析的結果作為 EL 和 沒用參數B 的EL結果的評估標準。根據評估,本研究提出了關於位移計算的修正係數、獲得準確結果所需的地震動數量以及鉛心橡膠支承系統的設計程序。 最後,使用提出的建議和位於台北二區、裝載36 個鉛心橡膠基礎隔震器的15 層抗彎鋼構隔震系統架成功執行了驗證過程。驗證過程包括NRHA、EL 和沒用參數 B 的EL 所有方法。此外,非線性歷時分析的結果亦用於評估 CF1 和 CF2 在預測基礎剪力方面的效果。 | zh_TW |
dc.description.abstract | Pulse-like ground motions are defined as ground motions, typically observed at sites located near the fault, with one or more pulses in the ground velocity history. Such ground motions can produce severe damage and large demands for base-isolation systems. Using additional viscous dampers can be a way to reduce the large displacement demand, but it will have additional force transmitted to the superstructure. However, there are only a few researches investigating the efficacy and accuracy of the commonly used equivalent-linear design procedure of isolation systems with additional viscous dampers compared to the nonlinear response-history analysis either subjected to non-pulse-like ground motions or pulse-like ground motions. This thesis thoroughly evaluated (1) the accuracy and efficacy of the equivalent linear (EL) method specified in current ASCE 7-16 and AASHTO 2010 and the equivalent linear method without B factor for the design of LRB systems with additional viscous dampers subjected to either non-PLGMs or PLGMs, (2) the influences of exponent of viscous dampers (αd) on structural responses, and (3) the efficacy of the load combination factors (CF1 and CF2) of the simplified method on predicting base shear force. A non-pulse-like ground motion database and a pulse-like ground motion database were established using the subset of the ground-motion databases of the PEER NGA West2 project and the SSHAC Level-3 project of NCREE Taiwan. Some criteria are adopted for the non-pulse-like ground motion selection process including 1) earthquake magnitude greater than or equal to 6.5, and 2) the closest distance less than or equal to 20km. Moreover, criteria such as scaling factor between 0.25 and 4 is adopted in the scaling process of both ground motions databases. 21SDOF models consisting of three types of Qd, two kinds of ξd, and three types of αd were used to perform the nonlinear response-history analysis, equivalent linear, and equivalent linear without B factor methods. The NRHA results were used as an evaluation benchmark for the results of the EL method and EL method without B factor. Based on the evaluation, a modification factor regarding the displacement calculation, the number of ground motions needed to obtain a reliable result, and a procedure were proposed for the design of a lead-rubber-bearing system design with additional viscous dampers subjected to pulse-like ground motions. Last, a validation process was successfully performed using the proposed recommendations and a 15-story base-isolated steel moment-resisting frame with 36 lead-rubber base isolators located in the Taipei Basin Zone Two. The validation process consists of all nonlinear response-history analysis, equivalent linear, and equivalent linear without B factor methods. Moreover, the NRHA results were also used to evaluate the CF1 and CF2 of the simplified method of MCEER in predicting maximum base shear force. | en |
