Wooden structures with connections on tree nails connectors PhD, Assoc. Prof. S.А. Isupov

For 25 years (from 1980 to 2005), wooden structures with connections on tree nails connectors have been used in the construction of 10 warm sites, 10 saw mills workshops, 9 manufacturing facilities, 2 sports centers, as well as the pavilion at the central market, constructions for Kirov Theatre Square decoration, and in other industrial buildings.

Study of building coating frame-membrane steel constructions PhD, Assoc. Prof. М.А. Zhandarov

Method of calculation and the study of plane prestressed cylindrical membranes:

- membranes with a uniformly distributed load; - membranes with a concentrated load; - membranes under the action of uniformly distributed and

concentrated loads; - calculation of membranes with bending stiffness (profiled decking); Structural designs of frame-membrane systems : - paving block; - space panel; - amplification circuit of rod constructions with flat membrane ; - prestressed panel.

Development of rods and assemblies for CCM frames:

Perforated beam with chess wall perforation; Perforated arch with chess wall perforation; Node rods connection of space frames; Prestressed flexible ground anchors; Flat thin sheet connection with skeleton prestressed membranes.

Collaboration of rod frames with a flat prestressed skin: Reinforcement of rods compressed in the plane of the membrane; Turning to the work of the stretched rod frame flat membrane; CCM, that provide a variable amount of reinforcement rods of compressed

frame.

2-nd Research Area

Investigation of the stress-strain state of the exploited reinforced concrete structures, methods of calculation and ways to strengthen the elements and parts of buildings

Prospects for research directions: ASSESSMENT OF DEFECTS OR DAMAGES FOR BEARING

CAPACITY OF CONCRETE ELEMENTS;

RESTORATION AND ENHANCEMENT OF CARRIER ABILITY OF FLEXIBLE CONCRETE STRUCTURES BY THE INTRODUCTION OF PRESTRESSED PUFFS OF DIFFERENT TYPES;

RESTORATION AND ENHANCEMENT OF CARRYING CAPACITY OF FLEXIBLE CONCRETE STRUCTURES BY THE INTRODUCTION OF UNRACKED AREA OF CONCRETE;

Research Objectives : Ordering of defects and structural damage in the Kirov region. The strength and stiffness of the normal sections of reinforced concrete

flexural members reinforced under load by increasing the tensile reinforcement installation of an additional prestressing reinforcement in the form of various puffs :

- horizontal; - trussed; - combined.

Investigation of the mechanism of the influence of debonding with concrete reinforcement (in the form of longitudinal cracks and corrosion zones collapse of the protective layer of concrete) on the strength of the normal sections of reinforced concrete elements.

Development of methodology for accounting debonding on the strength and deformability characteristics of bent reinforced concrete elements.

Investigation of the stress-strain state of the exploited concrete structures.
