新版規範鋼筋混凝土二元系統特殊結構牆設計

Abstract

本研究旨在探討臺灣即將公告新版鋼筋混凝土(RC)設計規範，該規範主要以ACI 318-19[1]為基礎，再根據我國研究成果修訂而成。規範中抵抗地震力的結構系統有兩種，分別為特殊抗彎矩構架與特殊結構牆，其中關於特殊結構牆之規定有大幅度的修訂，主要的修訂包括結構牆設計剪力之提高以及新增與修訂許多韌性配筋細節，設計剪力之提高係為考量非線性動力效應與超額強度之影響，而韌性配筋細節係為確保特殊結構牆具備良好的韌性與消能行為。 本研究將根據新版RC規範，對台北一區的案例建築進行使用特殊結構牆二元系統之設計，探討在符合臺灣工程業界的實務設計經驗與新版規範的設計規範下，從模型建置到配筋細節，歸納出特殊剪力牆的設計流程，以及模型參數設定之建議及相關設定探討。本研究將使用CSI-ETABS v9作為分析軟體，建立3D模型進行分析與設計。

This research aims to investigate the forthcoming announcement of Taiwan's new version of Reinforced Concrete (RC) design code, primarily based on ACI 318-19[1] and adapted to our country's research findings. The seismic resistance structural system specified in the code comprises two types: Special Moment Resisting Frames (SMRF) and Special Structural Walls. There have been significant revisions to the provisions for Special Structural Walls, including an increase in the design shear force and the addition and modification of several ductility reinforcement details. The increase in design shear force aims to consider the effects of nonlinear dynamic response and overstrength. The ductility reinforcement details are introduced to ensure that Special Structural Walls exhibit excellent ductility and energy dissipation behavior. In this study, based on the new RC code, we will design a case building in Taipei using the dual system of Special Structural Walls. The objective is to explore the design process of Special Shear Walls, from model creation to reinforcement detailing, while adhering to Taiwan's engineering industry's practical design experience and the new version of the code. Additionally, we will provide recommendations for model parameter settings and relevant discussions. To conduct the analysis and design, CSI-ETABS v9 will be utilized as the analytical software to establish a 3D model.
