Serviceability Criteria for Buildings in Mine Subsidence Area - Adjustment to Eurocodes

Abstract

Due to ground deformations caused by underground mining, building structures in mining areas are frequently subjected to considerable deformations and damage to the finishing and structural elements. As a consequence, serviceable values of such structures are distinctly diminished, and in extreme cases, seriously damaged structures may be exempted from further service. These problems are not duly represented in the existing building standard codes. It is also important to determine relationship between damage stage and value of the building, and hence the strategy for reconstruction or renovation works. The paper presents proposals concerning serviceability criteria of building structures in mining areas, in terms of basic standard requirements valid in building in Poland, as well as proposals of Eurocodes. Building structures under consideration have been divided into structures designed to resist mining influences and existing structures, not adapted to conform to these influences at the design and erection stages.

INVESTIGATION OF mE ALLOW ABLE DEFORMATIONS OF BUILDINGS SUBJECTED TO MINING INFLUENCE

“…Although proposals for the unification of some serviceability criteria (Digest 1990) or for the creation of more general model procedures undertaken in shaping the performance concept of buildings (Becker 1993) have recently been made, the method presented below has been designed by the author basing on his own experience. The discussed method is fully consistent with the general serviceability criteria of building structures in mining areas formulated by Kawulok and Sulimowski (1994), and based on two assumptions which have a direct impact on the serviceability of structures:…”

“…The concept of mitigated conditions for the serviceability of buildings in mining areas was presented during ASSMR. conference in 1994 (Kawulok, Sulimowski 1994 ), entailing the acceptance of the lowered criteria of the performance of buildings subjected to mining influence as compared to the generally obliged standards.…”
