Feasibility study and implementation of BIM in small scale projects
Authors: Munagala Devi Priya , Kone Venkatesh 
Published: September 2020

Abstract
Quality, cost and time are the 3 most crucial factors in any construction project. In fact, the success of a construction project is determined by how well these three elements are managed throughout the project. Even though, there are many traditional methods and software’s to provide assistance in this process but more often than not, they are proven to be expensive and error prone. In the last few years, the construction industry has witnessed a spur in the use of more advanced software’s and tools, thanks to the rapid technological advancements, and one of them is the emergence of Building Information Model (BIM). At present BIM is mainly used in managing large scale projects and has become the most important factor for the success of many such projects all over the world. While this paper tries to explore the feasibility and the practical problems arising in the process of adapting BIM even for small scale projects, it also proposes few methods on how to overcome these issues. It also highlights that following these methods will help to reduce the overall project cost by 20-30% and project completion time by a significant 80%.

Published: September 2020

Abstract
This study presents to determine the optimum values of the design parameters in High-Performance Concrete (HPC). Three design parameters considered for this study, such as Binder/aggregate, Superplasticizers. An orthogonal array was formed with the help of design parameters; optimization was done using the Taguchi method. The mechanical properties were studied in different specimens with different fiber ratios. When the HPC has very high in compressive strength, at the same time, brittleness of the concrete also high. There is a need to improve the ductile of the high-performance concrete. Due to fiber added to the mix, it enhances the strength of the concrete. Fibers are used in concrete to control the concreting, better toughness. Fiber pullout and fiber debonding are two toughening mechanisms provided by the fibers in concrete. Microstructure Study was conducted by using SEM images; it gives the interaction between the materials in concrete. The experimental and microstructure models were compared in this study for M80 concrete.

Authors: Prabha R , Kalaiyarasi R 
Published: September 2020

Abstract
A set S of isometric paths that partition the vertex set of a graph G is called an isometric path partition of G. The isometric path partition number of G is the minimum cardinality of such a set S in G. It is denoted by ipp(G). The isometric path partition problem is to find a minimum isometric path partition of a given graph G. The isometric path partition problem has wide applications in the designing of an efficient algorithm in many architectures. The problem of determining the isometric path partition of a given graph G is NP-complete and hence it is interesting to compute the exact value of isometric path partition of different networks. In this paper, we study the isometric path partition problem of butterfly networks, complete binary trees, rooted complete binary trees, X–trees and compute the isometric path partition number of these graphs.

Authors: Aarthy Reddy R , Balasubramanian M , Selvam Gopinath 
Published: September 2020

Abstract
Resource leveling is utilized to minimize the resource deviation with a uniform distribution of available resources. Herewith the study is to measure the impact attained due to the variation of input parameters such as the number of chromosomes and generations on resource utilization histograms. A good selection of the internal parameters of a genetic algorithm provides rapid and accurate results. We studied the effects of change in a key parameter, namely the number of chromosomes and number of generations, on the optimization speed and reliability. We found that changing one parameter can be compensated for changing another. For this purpose, different combinations of chromosome count and generation count were used to optimize via a genetic algorithm-based model. The network for evaluation of the framed model was structured based on site observation. The change in the input parameters gives greater impact to the resource histogram. To analyse the impact, various combination of input parameters is implied. The quality of the result is measure with an objective function. By using a meta-GA, we found the possible change in attaining optimum results using different chromosome count and generation count.

Authors: Kaavya D , Divya Krishnan K , Ravichandran P T 
Published: September 2020

Abstract
In order to deal with the geotechnical problems and with reference to the structural point of view, there arises a concept of combination of shallow and deep foundation i.e. combination of raft and pile foundation where the piles could be both connected and disconnected from the raft known as piled raft foundation (PRF) and disconnected piled raft foundation (DPRF). In this experimental study, analysis was done on raft, piled raft and disconnected piled raft under vertical loading by varying the compactness of cohesionless soil as loose and medium density and the thickness of cushion. The geotechnical parameters such as the bearing capacity and the settlements in foundation were analyzed. It is observed that the bearing capacity in DPRF and PRF was increased 38% in loose; 74% and 75% in medium compactness sand respectively when compared to raft foundation. Settlements were also reduced to 44% in DPRF in medium compactness of soil for raft size 150x150 mm with pile length of 200mm. The optimum cushion thickness in DPRF was achieved where H/B=0.34. Thus, to meet the stability requirements of high-rise buildings, structures built in weak soils and to resist horizontal loading, the DPRF which is effective and economical can be employed.

Published: September 2020

AbstractThis study emphasizes the rainfall analysis in the state of Sikkim located in the north east region of India, which covers up an area of 7097 km2. The rainfall analysis of the two districts East Sikkim and South Sikkim for a period of 118 years (1901-2018) are computed. Various tests depicting the trends, homogeneity, slope and statistical data reveals the monthly, seasonally and annual rainfall pattern in these districts of Sikkim. For the annual rainfall, the coefficient of variance varies from 13% to 19% whereas the coefficient of variance for seasonal rainfall varies from 14% to 81% which indicates that seasonal variability is more than the annual variability. Southwest monsoon contributes 79% to the annual rainfall followed by pre-monsoon which contributes 14% to the annual rainfall. The trend analysis depicts an insignificant increasing trend annually but a significantly decreasing trend for the south west monsoon with a negative slope justifying the downward trend. The homogeneity test points out the specific year the trend of the rainfall begins which was found to be in the year 1955.

Published: September 2020

Abstract
The article is devoted to the use of mechatronic sliding complexes for the construction of high-rise monolithic buildings and tower-type structures made of reinforced concrete. It is shown that high-rise monolithic towers of variable radius, characterized by the increased complexity of technological operations can be erected with high efficiency using automated sliding formwork, which makes it possible to achieve the highest possible pace of construction technology, while ensuring the high quality of work using self-compacting high-strength concrete. A mathematical description of the mechatronic complex as a completely observable multidimensional object with control limitations is given, which allows predicting deviations and deformations of the sliding formwork working platform design during the lifting process, evaluating the internal and external disturbances’ effect on the complex’s operation, and also modeling the interaction of the lifting and regulating mechanisms in violation of their synchronous operation. It is proposed to use the two-level systems to control the formwork lift and synchronize the movements between the actuators groups. The results of modeling the sliding formwork lifting process are presented.

Authors: Abakarov A D , Zaynulabidova H R , Omarov H M. 
Published: September 2020

Abstract
Real earthquake records differ from each other in a number of spectral parameters, the main one of which is the prevailing oscillations period. It usually varies over a wide range.
This work is devoted to the study of the seismic isolation systems’ sensitivity with a sliding foundation belt, kinematic supports and rubber-metal supports to the prevailing period of strong seismic impact. The studies were conducted on the example of a 5-story building with a rigid structural solution with seismic isolation in the foundation part. Seismic impact is presented as a synthesized accelerogram. The main attention is paid to the maximum movement of the building at the seismic isolating supports’ top level, which in reality is limited based on the supports stability and (or) the utility networks safety in the building. The seismic reaction dynamic calculations’ results of the systems under consideration are presented. It is shown that seismic isolation systems with an increase in the predominant period of seismic impact of 9-point intensity lose their advantage and the maximum displacement of the building with long-period influences becomes unacceptably large).

Published: September 2020

Abstract
Pipe concrete as a complex material, which effectively combines the advantages of steel and concrete, is used in the construction of high-rise and long-span structures and has good prospects for expanding the scope. At present, this is prevented by the relatively poor knowledge of the steel shell interaction with the concrete core under operational loads, when, due to the difference in the coefficients of transverse deformation of steel and concrete, the shell can detach from the core and lose its stirrup effect, which significantly increases the concrete strength. In the article in a linear-elastic formulation, the Lame problem is applied to a circular cylinder subjected to internal (for the shell) and external (for the core) uniform radial pressure, as well as an external centrally applied the longitudinal compressive force. The formulas for determining the stresses and radial displacements in the shell wall and core are obtained. The recommendations on providing the conditions for the joint operation of the shell and core, which are relevant, in particular, for the pipe-concrete kinematic racks of foundations protecting the buildings under seismic effects, are given.
