This book is the personal experience of the seniors who have taken part in the structural professional exam over the years, and contains too many ups and downs of preparing for the exam, as well as the excitement and joy of passing the exam.It is hoped that colleagues who are preparing for the exam can find their own review methods, learn from the experience and lessons of those who pass, and avoid detours. This book is divided into 7 sub volumes. Be sure to download all the sub volumes before unzipping them. After unzipping, the size is 7M.
Summary of past years' experience of Yizhu professional examination (PDF format)

Given the section size b * h, bending moment M, compression reinforcement As', calculate the tensile reinforcement As.If the calculated compression height of concrete x<2as', take x=2as', and take the moment M=fy * As * (ho as') for the resultant force point of compression reinforcement to calculate As.This is a common algorithm, and another algorithm is as follows: if the calculated concrete compression height x<2as', take As'=0, recalculate the compression height x according to the single reinforcement section, and then calculate As.Shi Lanqing's books are based on the first algorithm, while Xu Jian's books use two algorithms, and then take the smaller value for reinforcement.Sometimes the tensile reinforcement calculated by the second method is smaller.
