THE PROTECTABILITY OF BLOCK COVERINGS OF INDUSTRIAL BUILDINGS WITH DEFECTIVE LOAD-BEARING STRUCTURES FROM PROGRESSIVE COLLAPSE

Vestnik MGSU 9/2015

Beginning with the 20th century metal structures are widely used in the construction branch in Russia. The reason for it was in the development of calculation methods of structures. Beginning with 1930 and till now a substantial number of the industrial buildings (about 90 %) of production plants have been built of metal structures. The essential part of them - 20…60 % of the whole volume - has block coverings consisting of bearing and braced elements. At the present time the data on the operation duration of industrial structures is not systemized throughout Russia. This data may serve as one of characteristic factors for estimating safety operation level, because while the operation term increases, the wear also increases (mechanical damages), which influences the bearing capacity of the structures. The following article examines the collapse of industrial building coverings that may be accompanied not only by material losses, but also by fatal accidents. Statistical data of damageability of trusses and their elements are presented; the consequences of collapse are examined. The average life time of trusses is determined which is serving as a criteria that characterizes damage accumulation. The nature of the collapse of block coverings is revealed which, in most cases, may be classified as progressive.

At the present moment prevention of emergencies of buildings and structures is still the priority direction of investigations in the construction branch. The statistics shows that the possibility of 25 crashes a year is 1,0, and in case of human losses - 0,3. The great number of these emergencies is of a progressive character, when a local crash leads to the crash of the whole construction or of the great part of its structures. We should note that also industrial buildings are among the buildings where major accidents happen. And their number is growing with every year. The following article examines the problem of progressive collapse in block coverings of industrial buildings when the failure of one truss results in the collapse of the entire block. The overview of experimental investigations of the construction elements of block coverings is carried out. The methodology of experimental investigations of block coverings under emergency influences is introduced. The following article also introduces the results of experimental investigations. The numerical modeling of the block covering model is introduced and the comparative analysis with experimental data is performed.

In the large cities of Vietnam there is a serious problem of providing the drinking water of good quality to population and industry in the required quantity and with sufficient pressure. Chaotic building in certain areas has resulted in the formation of quite complex water systems, consisting of large main pipelines and a plurality of dead ends. Because of insufficient water pressure in the water network, the majority of consumers have to install individual reservoirs and tanks on the roofs of the buildings. The uneven water withdrawal from the network and its irrational use violates the hydraulic regime of water supply and distribution. The authors offer a water supply scheme with the accompanying transit flow lines with pipes of smaller diameter which allow providing the required amount of water and increasing the pressure on the ring. Hydraulic calculations of ring network were made using the software program WaterGEMS V8i for the worst case of the system of water supply. The plots of the water supply network show an increase in diameter of pipes is required, which greatly reduces pressure losses and ensures a reliable supply of water to the consumer. In order to solve the problem of optimal power flow, a scheme of water supply with associated main pipelines with smaller diameter was created. Laying of main pipelines accompanied by parallel lines connected to them provide better hydraulic conditions, reduce the pressure loss in the piping and shortens power consumption.
