Chinese Abstract

本文主要目的在探討鋼結構包覆鋼筋混凝土外牆後對鋼構桿件內力之影響,並比較樓層之樑柱桿件在各種不同牆厚下與無牆下之比例關係,完成不同牆厚鋼結構桿件的斷面設計,以今年年初(97年2月)之工程單價分析,完成各案例結構體建造成本分析,以供日後工程師設計類似建物時參考使用。本文研究對象設定為中小型之鋼構造倉儲廠房,以其12㎝及20㎝設定外牆厚度,在ETABS 中建模及執行分析,統整出樑柱桿件在有牆與無牆時各項內力差異之百分比。 研究發現含牆之結構物,在鋼構桿件分析時會因牆體對結構載重的貢獻,降低鋼結構桿件因載重而產生的內力,又以柱桿件內力折減較樑桿件大。同時結構體受力後柱桿件產生之剪力(V2),相較於無牆的案例,各有牆案例之柱桿件剪力平均值在無牆案例16%以下,同時彎矩有牆及無牆案例比較,有牆案例彎矩下降為無牆案例15%以下。 結構分析時考慮牆構件之結構效益,在本研究中可使整體鋼構桿件重量(成本)降低25%。但在兩不同厚度牆體的分析案例中,並未使兩個案例之鋼構桿件重量有明顯的差別,兩不同牆厚之鋼構桿件整體重量差異在4%內。

English Abstract

Abstract This study aims to explore the impact on external walls of reinforced concrete coated steel structure after internal forces function of the steel rods, and compare the percentage relations between the bar and beams of each floor in a variety of different thickness of the wall and no wall structure, and to complete the section design of steel rods on different wall thickness. Based on the analysis on unitary price for the works in the beginning of this year (February, 2008), the construction costs analysis for each case is completed and it is used as reference for the similar buildings constructed and designed by the future engineers. In this study, the small and medium-sized steel storage plants are targeted with 12cm and 20cm external wall thickness, and in ETABS modeling and analysis implementation, the percentage difference between the internal forces of the beams to a bar in the wall and no wall is integrated under management. This study found that the wall structure, in the analysis of steel rods, is contributed to the heavy-duty steel structure and to reduce the internal forces of the beam bar and to lower the internal forces of the bar on the heavy-duty steel structure. At the same time, the generated shear (V2) created by the structure of the force after the pole pieces, in comparison to the case without walls, the shear walls average value of each wall case is under 16%. Meantime, compare to the cases of the moment with wall and without wall, the moment with wall case fell under 15% if compared to the no wall case. When in the structural analysis considering about the effectiveness of wall component of the structure, this study enables to decrease 25% of the overall weight of steel rods (cost). However, in two different wall thickness of the cases, there are significant differences for the two cases with weight of steel rods, and the difference of overall weight of steel rods for two different wall thickness is within 4%
