FIRE RESISTANCE OF REINFORCED CONCRETE SLABS ACCORDING TO EC2 AND BRANZ TR8
Concrete elements are practically an integral part of every construction project andbuilding. They have significantly higher fire resistance in comparison to elements madeof other construction materials. However, RC slabs are the most sensitive concreteelements to the effects of fire when compared to all the other reinforced concrete elements.There...

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...

STUDY ON SEISMIC REINFORCEMENT MEASURES AND SCHEMES OF IRREGULAR FRAME STRUCTURES
The SAP2000 finite element analysis software was applied to model the original frame and carry out the elasto-plastic time-history analysis method, with an existing irregular plane framework in Tianjin as the object of the study. Buckling-Restrained Brace (BRB) damping and anti-torsional reinforcement scheme was proposed based on the analysis resul...

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...

ASSESSMENT OF HUMAN EXPOSURE TO VIBRATION AND NOISE IN RESIDENTIAL BUILDINGS
Vibration in buildings may occur from different external or internal sources. Where occupants can detect vibration in buildings, it may potentially impact their comfort or working efficiency. Some vibration sources give rise to audible effects such as structure-borne noise and airborne noise, and secondary rattling of building elements or contents....

DIGITAL MODELING OF EARTH'S SURFACE RELIEF
This paper presents the theoretical basis for the development of the Earth's surface relief digital models. The sources and structure of the modeling data, as well as the methods of their processing, are described, depending on the spatial-temporal properties of the Earth's surface. Digital relief models have great significance and wide application...

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 ...

ULTIMATE STRENGTH OF COMPRESSED SLABS AND BOX GIRDERS
A theoretical investigation into the effectiveness of a plate thickness against the ultimate strength of a compressed slabs and box girders is carried out. Series of the buckling analyses, the elastic, the viscoplastic and the ultimate strength are performed by the rheological-dynamical inelastic theory and the finite strip method on a slabs and bo...
