摘 要

   本工程為政府辦公樓工程，采用框架結構，主體為六層，本地區抗震設防烈度為8度，近震，場地類別為II類場地。主導風向為西南，基本風壓0.40KN/M，基本雪壓0.25 KN/M。樓﹑屋蓋均采用現澆鋼筋混凝土結構。

   本設計貫徹“實用、安全、經濟、美觀”的設計原則。按照建筑設計規范，認真考慮影響設計的各項因素。根據結構與建筑的總體與細部的關系。

   本設計主要進行了結構方案中橫向框架第12軸抗震設計。在確定框架布局之后，先進行了層間荷載代表值的計算,接著利用頂點位移法求出自震周期，進而按底部剪力法計算水平地震荷載作用下大小，進而求出在水平荷載作用下的結構內力（彎矩、剪力、軸力）。接著計算豎向荷載（恒載及活荷載）作用下的結構內力。是找出最不利的一組或幾組內力組合。 選取最安全的結果計算配筋并繪圖。此外還進行了結構方案中的室內樓梯的設計。完成了平臺板，梯段板，平臺梁等構件的內力和配筋計算及施工圖繪制。對樓板進行了配筋計算，本設計采用樁基礎，對基礎承臺和樁進行了受力和配筋計算。

   整個結構在設計過程中，嚴格遵循相關的專業規范的要求，參考相關資料和有關最新的國家標準規范，對設計的各個環節進行綜合全面的科學性考慮�？傊�，適用、安全、經濟、使用方便是本設計的原則。設計合理可行的建筑結構方案是現場施工的重要依據。

ABSTRACT

   This works for the city of Luoyang West office building, a framework structure for a six-storey main, in the region earthquake intensity of 8 degrees near Lan site classification as Class II venues. Led to the southwest direction, the basic Pressure 0.40 KN / M, basic snow pressure 0.25KN/M. Floor roof were using cast-in-place reinforced concrete structure.

   The design and implement "practical, security, economic, aesthetic," the design principles. With the architectural design, design seriously consider the influence of the various factors. According to the structural and architectural detail and the overall relationship.

   The design of the main structure of the program horizontal framework 12-axis seismic design. In determining the distribution framework, the first layer of representative value of the load, Then use vertex from the displacement method for earthquake cycle, and then at the bottom of shear horizontal seismic load calculation under size, then calculated the level of load under the Internal Forces (bending moment, shear and axial force). Then calculate vertical load (constant load and live load) under the Internal Forces. Identify the most disadvantaged group or an internal force several combinations. Select the best safety results of the reinforcement and Mapping. In addition, the structure of the program indoor staircase design. Completion of the platform boards, boards of the ladder, platform beam component and the reinforcement of internal forces calculation and construction mapping. On the floor reinforcement calculation, the use of pile foundation design, foundation and pile caps for the force and reinforcement calculation.

   The whole structure of the design process, in strict compliance with the relevant professional standard, reference to relevant information and the latest national standards and specifications, and design of the various components of a comprehensive scientific considerations. In short, application, security, economic and user-friendly design is the principle. Design reasonable and workable structure of the program is the construction site of the important basis for the construction.
