Abstract

The theory which consists of two parts: short-term and long-term loading and of five inconsistent (or erroneous) theories that reject the fundamental properties of structural concrete and the principles of Eurocode and which is used in the calculations of various buildings and structures is analyzed.

Highlights

  • Each part is based on arbitrary fundamental delusions caused by inconsistencies in the system of general theory [2]

  • The analyzed theory is preceded by an explanation in the form of two Provisions in a number of works as well as in the norms: I - it is necessary to use a nonlinear deformation model; II - it is allowed to calculate on the analyzed theory basis

  • One of the norms developers in 2011 warned that an ordinary designer would not be able to use Regulation I: “The deformation model of force resistance is mainly implemented through the computing systems, so here a number of formal procedures arise, for example, stability, the solution accuracy estimation

Summary

Introduction

There are mathematical errors in it: the fundamental concepts of classical and general theory of calculation are distorted; the design principle of the bearing capacity by the limit states, the process of continuous structures’ loading established by Eurocode, is rejected; the properties of structural concrete fundamental according to Eurocode are replaced; the links to abstract experimental results are provided

Results
The analyzed theory features
The theory of a structure that has no length
IE t l2
The distorted Euler problem
Erroneous theory of concrete linear creep
