GEODETIC MONITORING OF STABILITY OF THE CONSTRUCTION PIT DIAPHRAGM OF THE OBJECT
High-rise building, today, is characterized by the construction of facilities that are higher and more complex in their geometry, and are often located in the narrow city core where numerous facilities have been built in a small area that additionally complicate the execution of construction and geodetic works. In order to obtain information on the...

SOME NUMERICAL ASPECTS OF A LINEAR STATIC ISOGEOMETRIC ANALYSIS OF AN ARBITRARILY CURVED PLANE BERNOULLI-EULER BEAM
Linear static analysis of arbitrarily curved beams is considered. Metric of a Bernoulli-Euler beam is rigorously defined and the weak form of the corresponding boundary-valueproblem is solved using isogeometric approach. Driving force behind present research isdetail numerical analysis of recently developed model of an arbitrarily curved beam. This...

EMPIRICAL DETERMINATION OF THE FUNDAMENTAL PERIOD OF FREE VIBRATION OF RC BUILDINGS
Determining the value of the fundamental period of vibrations of reinforced concrete structures is a complex task. In order to have certain data on the fundamental period of vibration in the earliest design stage, engineers use various approximate methods, which can quickly and simply, but still sufficiently accurate, provide an estimate of the req...

WATER PERMEABILITY OF ROCK MASS
The presence of water in the rock masses, or water filtering, has an important role in theconstruction of engineering facilities (dams, tunnels, ...), as well as in formation of rockslopes, caused by the implementation of various projects. The rock mass, that we find innature (in-situ), is heterogeneous, anisotropic, jointed and is in the natural s...

THE INFLUENCE OF CONCRETE VISCOUS DEFORMATIONS IN THE CALCULATION OF THE HIGH-RISE BUILDINGS BEHAVIOR OVER TIME
An example of a high-rise building behavior calculation shows that weather deformations of concrete have a significant contribution to changing the behavior of vertical load-bearing elements - columns and walls. The phenomenon of different shrinkage of concrete/steel pillars and concrete core due to the shrinkage and creep of concrete over time is ...
