Influence of New Apertures and Elements of Amplification on Intense – Deformed Condition of Elements of Buildings at Their Reconstruction

December 18, 2014

ABSTRACT

In article results of numerical researches of tensely – deformed conditions of external and internal bearing walls of a building after its partial reconstruction with the device of new apertures in internal walls and strengthening of piers and existing apertures in external walls are analyzed.

The volumes  of reconstruction which have increased recently and re-planning of residential buildings with change of purpose of maintained premises demand the concidered approach to the analysis tensely – deformed conditions (IDC) of constructive elements of these buildings, that considerably increases required amount of calculations. In case of influence on a building of non-uniform deformations of the basis under complex earth conditions, the responsible design decisions supported by numerical researches of change of the IDC of bearing elements of a building at their reconstruction are required. Thus not always there is an opportunity of calculation of all building on detailed spatial model, taking into account besides, that such calculations considerably increase cost of designing.

With the purpose of simplification of carried out calculations in Zaporozhye State Engineering Academy (ZSEA) researches are lead and recommendations on drawing up of the simplified settlement models of frameless buildings and their elements are developed. Thus influence of the accepted simplifications and changes of various parameters of settlement models on IDC of bearing elements of so-called “buildings – representatives” which are characteristic buildings under constructive characteristics, time of construction, to conditions and features of operation among the most widespread series or types was investigated.
