There are 16 questions in the steel structure part of the first level registered structural examination in 2022. This year, there are several new features and new questions different from the past.
Analysis of new test points for steel structure
I, The 2022 exam will pay more attention to the derivation of formula according to the balance of force , rather than the existing calculation formula in the specification, such as calculating the area of the anchor bolt of the column base plate according to the stress state, or calculating the bolt diameter of the end plate connection.
2、 There are many new test points that have not appeared before, for example, two questions are given when the pin is connected in one breath.
III, Even in the previous exam sites, the calculation is also very heavy, so people report that the difficulty is high, and the success rate is low, It is not like the previous exam, which only intercepts a small part of the parameters. For example, for out of plane stability, all parameters need to be calculated. For example, for calculating the column length coefficient, not only with and without support, but also with the maximum and minimum axial force and other different situations should be considered! Finally, we should also remind that traditional knowledge points can not be ignored, at least accounting for about 10%!
15 steel structure calculation questions and 1 concept question in 2022 。 Among them, the traditional examination questions such as steel column calculation length, stability calculation, crane influence line, composite beam stud, column bracing, crane beam local pressure, node area, etc. should be able to be taken as long as the knowledge points are thoroughly understood. New examination questions, such as column base plate anchor bolt, end plate connecting bolt, pin shaft checking calculation, pay more attention to design principle and stress analysis. It should be said that only four examination questions may lose points. according to 80% accuracy, 16x80% ≈ 11 points, steel structure 11 points should be able to get.
The score proportion of steel structure examination questions is increasing
Percentage of steel structure examination scores in the first level registered structural engineer examination:
one 、 From 2011 to 2019, 14 points in the steel structure examination accounted for 17.5% of the total score
two 、 From 2020 to 2022, 16 points in the steel structure exam accounted for 20% of the total score
Percentage of steel structure examination scores in the second level registered structural engineer examination:
one 、 From 2011 to 2017, 12 points in the steel structure examination accounted for 15% of the total score
two 、 From 2018 to 2019, 14 points in the steel structure exam accounted for 17.5% of the total score
three 、 22 points in the steel structure exam in 2020, accounting for 22% of the total score
four 、 From 2021 to 2022, the score of steel structure accounts for 20 points, accounting for 20% of the total score. The score of steel structure examination increases year by year, and the proportion increases ！ So whether the score of steel structure can be obtained plays a decisive role in passing the examination of registered structural engineer!
How to get the score of steel structure examination questions
1、 Make sure to master and understand the common provisions and calculation formulas of steel structure standards and high steel specifications!
II Ensure that the blank volume of the real question can quickly find the corresponding provisions of the specification!
3、 Grasp the force analysis and design principles of common steel structure members, and enhance manual derivation of force balance equation
IV Establish a two-way bridge between norms and real topics. To ensure that the reading of the blank volume of the real question can quickly find the corresponding provisions of the specification ， Demonstrate the method of solving blank test papers of the past years' registered structural engineer examination, find out the key words from the reading question stem, quickly find the standard directory, and ensure the speed of solving steel structure questions by using the original reverse and positive problem solving methods. In view of the important position of steel structure in the registration examination, we specially（ 108 topics), another section selects the special class of steel structure code (23 topics), another section selects the special class of concrete code (22 topics), and another section selects the special class of masonry code (16 topics) from standard Principle analysis +Multiple authentic questions can be comprehended comprehensively and from multiple angles, and the mapping relationship between norms and authentic questions can be established so that the registration test scores of steel structures can be truly obtained! Taking the common calculation length as an example, the calculation length formula of various steel structure components and a large number of real questions are summarized to ensure that there is no dead angle covering this knowledge point.
