Abstract Due to growing population and less availability of land, multistoried buildings are constructed which can serve many people in less area. Purpose of this project is to analysis and designs (G+13) multistory building using E-TABS. Aims are to give proper awareness regarding right design and details of the building. Planning is done using AutoCAD, Designs has involves Load calculations, manually and the Structure is analysis using E-TABS. Codes refer for these projects are NBC IS (456-2000). Concrete mix use is M30. The steel strength for all members is of grade Fe-415 & Fe500. For analyzing the structure, the loads are very important which are calculated using IS (875). The LIMIT STATE METHOD is the method which has been adopted. The manual design is a difficult process and consumes more time. The project purpose is to give the overall experience in the field of planning, design and to gain the knowledge in a practical way.

Due to growing population and less availability of land, multistoried buildings are constructed which can serve many people in less area. Main aim of this project is to analyse and design a (G+16) multistory building using E-TABS. Aims to give proper awareness regarding right design and details of the building. Planning is done using AutoCAD. Design involves load calculations manually and the structure is analyzed using E-TABS. Codes refer for this project are NBC IS (456-2000). Concrete mix use is M30. The steel strength for all members are of grade Fe-415. For analyzing the structure, the loads are very important which are calculated using IS (875). The LIMIT STATE METHOD is the method which has been adopted. The manual design is a difficult process and consumes more time. The project purpose is to give the complete experience in the field of design and to gain the knowledge in a practical way.

In order to ensure the safety of the scaffolding of the home block for hanging cradle construction, this paper makes use of probabilistic limit state method, and carries out the checking computation. According to the actual drawings of the Qinhe bridge and the actual load case, the analytical model is established through the finite element analysis software MIDAS/CIVIL. The results show that the slant tube may be flexural buckling, and the stress of side standing tube is over the design strength of material, so that there is potential danger of the scaffolding. After the horizontal tubes were installed along the boundary of scaffolding, the stresses of all tubes are less than the design strength of corresponding material.

Mechanical Properties of Confirmat Screws Corner Joints Made of Native Wood and Wood-Based Composites. The aim of this investigation was to design and determine the mechanical properties of confirmat screws corner joints made of native wood and wood-based composites. The objective of the study was to ascertain the stiffness and load carrying capacity of joints that differed in the diameter and length of confirmat type screw, as well as in the kind of materials. The results include statistical processing of measured and calculated data, and evaluation of the influence of selected factors on mechanical properties. The results are applied to the calculation of the characteristic values of the properties and to the determination of the equations for their calculation for other values of the selected factors. The characteristic values are used for the evaluation of the joints according to the limit state method.

Research Findings

The article addresses mechanisms of anchorage failure in a concrete base studied within the framework of physical experiments. The authors investigated the most frequently used types of anchors, such as the cast-in-place and post-installed ones. The anchorages were studied under static and dynamic loading, similar to the seismic type. During the experiments, the post-earthquake condition of a concrete base was simulated. Within the framework of the study, the authors modified the values of such parameters, such as the anchor embedment depth, anchor steel strength, base concrete class, and base crack width. As a result of the experimental studies, the authors identified all possible failure mechanisms for versatile types of anchorages, including steel and concrete cone failures, anchor slippage at the interface with the base concrete (two types of failure mechanisms were identified), as well as the failure involving the slippage of the adhesive composition at the interface with the concrete of the anchor embedment area. The data obtained by the authors encompasses total displacements in the elastic and plastic phases of deformation, values of the bearing capacity for each type of anchorage, values of the bearing capacity reduction, and displacements following multi-cyclic loading compared to static loading. As a result of the research, the authors identified two types of patterns that anchorages follow approaching the limit state: elastic-brittle and elastoplastic mechanisms. The findings of the experimental research allowed the authors to determine the plasticity coefficients for the studied types of anchors and different failure mechanisms. The research findings can be used to justify seismic load reduction factors to be further used in the seismic design of anchorages.

With EN 13001-1 ff. a harmonized set of standards for safety of cranes was and is established. Due to harmonization the use of the standards leads to the assumption of conformity with the safety requirements of the machinery directive. A major argument for the application of the standards. The standards comprise new concepts of proof of competence in comparison to previous standards. Keywords of these new concepts are “Classification”, “Limit state method”, “Mass Distribution Class” and “Partial safety factors”. The article gives an overview to EN 13001-1, EN 13001-2 and EN 13001-3-1. This is the set of standards for proof of the structural parts of a crane. The main aspects of the standards are shown and discussed with regard to their impact on calculation.
