结构设计与审查常见问题（Common issues in structural design and review） Some common problems of standard serial number processinspection agency comments Specification number entry A load and calculation part 1 Calculation of unidirectional seismic action, without considering the impact of occasional eccentricity. JGJ3-2002 3.3.3 rectification 2 for important or very sensitive to wind load of high-rise building the basic wind pressure according to the 100 year return period wind pressure value is used. JGJ3-2002 3.2.2 rectification 3 high-rise building fire evacuation stairs, load value is less than 3.5kn/m2. GB50009-2001 4.1.1 rectification 4 people on the roof live load are still using the old standard value of 1.5 kn/m2, the people on the roof should be non building professional confirmation, sometimes according to the design of roof structure non for roofs on buildings. GB50009-2001 4.3.1 rectification 5 of hotels, hospitals and other local toilet partition layout is dense, not converted into equivalent load according to the actual input, such as the wall weight per meter 1/3 reduced survival load value is too small, and more than 1 kn/m2. GB50009-2001 4.1.1 note 5 rectification 6 of the irregular plane structure, the first torsion vibration cycle pressure Tt and translational dominated the first period T1 ratio structure, A-class height more than 0.9 B, height is greater than 0.85. JGJ3-2002 4.3.5 rectification 7 of the mass and stiffness distribution is obvious asymmetry, uneven structure is calculated according to unidirectional horizontal earthquake. JGJ3-2002 3.3.2 rectification 8 of V shape, Y shape, curved, well shaped flat building, wind load shape coefficient is 1.3. JGJ3-2002 3.2.5 comments 9 cast-in-place floor in the stiffness of the beam increases the coefficient of 1, causes the beam reinforcement bearing small. JGJ3-2002 5.2.2 comments 10 degree 7-9, frame structure without weak layer test and checking GB50011-2001 5.5.2 audit opinion 11 underground building an
