What are the useful apps in the construction industry?

Master of Structure

Solver of Structural Mechanics of Mobile Terminal; Draw a line at the end of the finger, click to edit the node and bar element, and have a smooth modeling experience; Powerful, the internal force diagram includes axial force, shear force, bending moment, bearing reaction and structural deformation. It also supports influence line, dynamic mode analysis and geometric composition analysis; There is also an artificial intelligence module, which can output the steps of solving problems in mechanics textbooks.

Master of Structure can be regarded as my "famous work", but I am not very satisfied with it, mainly because it is a little troublesome to draw the structure with decimal point length, so I still use Tsinghua's structural mechanics solver for structural analysis sometimes, and I will solve this problem in the later update.

Master of Engineering Surveying

Convenient measuring calculator to assist measuring engineers in measuring and calculating; The main function is to control the calculation of survey traverse and the elevation adjustment of leveling; There are also some small functions such as coordinate inverse calculation, rendezvous and fixed point, angle conversion, etc., which can meet the actual needs of the site.

I am quite satisfied with this App myself, and the software has been recognized by many professionals, shortening the measurement and calculation process from half an hour to five minutes by mobile phone, greatly reducing the work of surveyors.

section steel master

quickly inquire about the geometric dimensions and mechanical properties of profiles; The profiles included include hot-rolled steel, hot-rolled steel bars (square steel, round steel, etc.), cold-formed thin-walled steel, steel pipes, steel plates, steel bars, rails and other stereotyped steel and steel components; The query content includes section size, unit weight, moment of inertia, inertia radius, section modulus, center of gravity distance, etc. Accurate data, all data are from the latest national norms and industry standards, handwritten by me and my friends; Whether it is identification symbol or decimal precision, all data formats are consistent with the specification; All parameters can be converted into units (mm/cm/DM/m/in/ft) conveniently in the software; You can also calculate the total weight according to the length, the slenderness ratio of the pull rod and the moment of inertia after shifting the shaft, which is convenient for designers.

This is also an APP that I can't put down. At work, I often need to check the section size or moment of inertia of a certain section steel, and I also need to know its own weight when calculating. At this time, I will take out my mobile phone and check my work.

concrete master

A small tool to help structural engineers calculate reinforced concrete structures. It can not only quickly calculate the bearing capacity of concrete structures, design reinforcement, display calculation steps, but also attach common knowledge points in concrete specifications for convenient and quick query. Suitable for designers, supervisors, structural inspectors, researchers, college students and other professionals, the modules currently included include: pure bending beam, pure shear beam, pure torsion beam, bending-shear-torsion composite beam, bearing capacity calculation of eccentric compression column and reinforcement design.

This version is not particularly perfect, and there may be some minor problems in the calculation results. Please look forward to my future update.

Master of Construction Calculation

The calculation tools commonly used by front-line construction personnel can query the conventional data of the construction site, such as the concrete strength grade and the anchorage lap length of steel bars, to calculate and analyze the complex construction scheme

Because the construction field covers a wide range, the author plans to improve this comprehensive App in two years.

Tool Applications specially made by rebar master

include calculation of rebar blanking length, inquiry of rebar anchorage lap length, inquiry of material weight and strength, and strong substitution of rebar, etc. It supports inquiry of 1611 standard atlas, and can quickly check relevant structural practices on site

This app is tailor-made for rebar turnover. For people who have dealt with rebar all their lives, it is necessary to use rebar master to facilitate their daily work ~ <

The above is designed and produced by my last sister in Zhihu. Most of the software is free and there are no messy advertisements ~
