the frame structure design of School of Mintai
General Description of The Design: This is the frame structure design of Maple's woods hotel. The structure is a cast-in-place reinforced concrete frame structure, which is five floors on the ground and structural maximum height is 18.210 meters. Total construction area is 9864 square meters. Building design service life is 50 years and fireproof rank is secondary. The seismic fortification intensity is 8 degrees. Design content is the structural design, including the determination of structure scheme, structure calculation and structural drawings. The determination of structure scheme is mainly according to the architecture diagram to selected the section size of beams and columns ，decorate the position of beams and columns , and consider the eccentric effect. Structure is mainly using PKPM structure calculation software modeling calculation to finish the reinforcement calculation of upper structure and foundation. Structure drawing is according to the calculation results to draw the reinforcement drawing of beam, floor and column, infrastructure layout and stair detail construction drawing.
For the number of teaching buildings to take masonry structure or steel structure is not very suitable for China's current actual materials and construction technology, the use of reinforced concrete structure is the most realistic and reasonable. In frame structure, frame shear wall and shear wall three structure system, using a five - storey teaching building frame structure is reasonable, in the proper reduction of the column net to avoid arrangement of shear walls is feasible, without losing its rationality, at the same time, it can perfectly suited for the graphic design of the room. Reinforced concrete frame structure. Floor and roof for reinforced concrete slab. The stairs are in place parallel to the stairs. Based on the use of pile foundation, the use of prefabricated piles. The characteristics of the pile foundation: deep buried deep foundation, the pile soil load transfer, or transfer to the deep soil of high strength, less compressibility, large bearing capacity, can withstand the vertical load, horizontal load and dynamic load, pile foundation through soil liquefaction, the load transfer to the stability of the liquefied soil great, the vertical stiffness of pile foundation settlement, small and uniform, with large lateral stiffness, large horizontal force, capable of resisting typhoon and earthquake caused by uplift force and overturning moment, to ensure the safety of high-rise buildings and high-rise structure, change the dynamic characteristics of foundation soil, reduce the amplitude of vibration frequency, improve the foundation, to ensure the normal operation of machinery and equipment, to avoid a lot of excavation, require special equipment, high cost. The scope of application of the pile foundation: the upper soft layer and the lower hard soil layer, uneven ground, or special foundation soil (overlying can be liquefied soil, expansive soil), towering structure, heavy structure and load distribution uneven structure, close to the adjacent buildings and large ground surcharge, precision or large equipment, building special environment: bridge, port and so on. : frame structure, column alone cloth pile, beam or frame colonnade consists of basic cloth pile (beam pile foundation; pile precast or cast-in-place. So this project uses the pile foundation.
Staircase design make it conform to the "code for fire protection design of buildings", the design of civil buildings "and other relevant single building design codes provisions, consider the requirement of fire, can direct natural lighting and natural ventilation.
Staircase is an important part of the housing, and determine the staircase layout, step size, railings and other forms of architectural design, stair slab and beam type stairs is the most common form of stairs. The plate type stair is composed of an inclined plate, a platform plate and a platform beam, and the utility model has the advantages of smooth surface, convenient construction, and light appearance. Now cast in situ beam type stairs treads, bevel edge beam, plate platform beam and floor beam, treads supported in the bevel edge beam and the wall, in against the wall with the bevel edge beam, bevel edge beam supported on the platform beam and floor beams (support at the lower part of the bottom of the stairs in Delong wall), its characteristics is suitable for large span staircase. 小学四层框架结构设计+CAD图纸(2):http://www.751com.cn/gongcheng/lunwen_49185.html
