WIND ANALYSIS OF A MULTI STOREY BUILDING WITH AND WITHOUT MASS IRREGURALITY B...

Divya Swapna Nallajeru

Structural Analysis is a branch which involves in the determination of behaviour of structures in order to predict the responses of different structural components due to effect of loads. Each and every structure will be subjected to either one or the groups of loads, the various kinds of loads normally considered are dead load, live load, earth quake load and wind load. ETABS (Extended Three Dimensional Analysis of Building System) is a software which is incorporated with all the major analysis engines that is static, dynamic, Linear and non-linear, etc and especially this Software is used to analyze and design the buildings. Our project “Wind Analysis of a Multi-storey building with and Without Mass Irregularity” is an attempt to analyze a multi storey building with Mass irregularity. A G+10 storey building is considered for this study. Irregularities are not avoidable in construction of buildings; Adequate precautions can be taken. A detailed study of structural behavior of the buildings with irregularities is essential for design and behavior. Civil engineering structures are mainly designed to resist static load. Generally the effect of dynamic loads acting on structure is not considered. This feature of neglecting the dynamic forces sometimes becomes the cause of disaster, Over the last two decades, Wind engineering has increasingly focused on the modest low rise and high rise structures, since much of the damage and financial loss associated with extreme wind events happens to these minimally engineered buildings like low rise buildings and also huge loss if encountered by the high rise buildings. As some of these model- and full - scale wind engineering data filters into the design codes and standards, one may expect to see reduced hurricane/cyclone damage. However, when one combines the more rapid increase in population along the world's tropical coasts with a generally unacceptably low standard of new building construction inspection, it seems quite likely that loss of life, as well as insured and uninsured property losses will continue to be the norm in the foreseeable future. The wind engineering community needs to be more responsible in forcefully transferring our technical knowledge to the designer and builder. In this present work the analysis for G+l0 Reinforced cement concrete building having mass irregularity in 9th floor and building without mass irregularity are analyzed. This thesis highlights the effects on floor which has different loads (mass irregularity) in multistorey building.

Sachpazis: Wind loading to EN 1991 1-4- for a hipped roof example

Dr.Costas Sachpazis

This document provides an example calculation of wind loading on a hipped roof structure according to Eurocode 1991-1-4. It includes details of the building geometry, terrain conditions, and calculation of peak velocity pressures and net pressures on different zones of the roof and walls. The results are tabulated forces on the roof and walls for two different wind directions. The overall net windward force on the structure is also calculated considering lack of correlation between windward and leeward pressures.

Shear box test

Natalie Ulza

The shear box test is used to determine the shear strength of soils. The test involves placing a soil sample in a copper box and applying a load to create shear stresses on a failure plane within the sample. Measurements of deformation, load, and shear stress are recorded to calculate shear strength parameters like cohesion and angle of internal friction based on Coulomb's shear strength equation. The test aims to determine the failure strength on a predefined surface and provides important data on the shear properties of soils.

Steel connections

babunaveen

Connections are critical structural elements that join members in steel structures. Common connection types include bolted, welded, and bolted-welded combinations. Connections are classified based on the connecting medium, type of forces transmitted, and elements joined. Riveted connections were previously common but have been replaced by bolted connections which are faster and cheaper to install. Welded connections provide rigidity but require careful design to avoid cracking. Modern connections often combine bolting and welding for strength and economy. Shear and moment connections behave differently in transmitting forces between members like beams and columns. Proper connection design is important for structural integrity and safety.

1) Dynamic forces produce non-uniform velocity and acceleration in structures, unlike static forces. Dynamic forces include those from rotating machines, wind, impacts, earthquakes, and suddenly applied loads. 2) Dynamic analysis is needed to accurately model structural response to dynamic loads like earthquakes and wind, as the assumption of static, slowly applied loads may provide non-conservative results. 3) Frequency content is an important parameter for characterizing ground motions, as it describes the distribution of amplitude across frequencies and influences structural response. Fourier analysis can be used to determine frequency content from time series data.

In the urban areas the level crossing is generally monitored by qualified railway personnel who monitor the train movement and close the level crossing gate to stop the interfering road traffic but such closing of gates leads to congestion in road traffic and also causes loss of time to road users. Road under bridge and road over the bridge are considered as solutions for avoiding level crossings of roads and railway track.

DESIGN AND ANALYSIS OF G+3 RESIDENTIAL BUILDING BY S.MAHAMMAD FROM RAJIV GAND...

Mahammad2251

Structural design is the primary aspect of civil engineering. The foremost basic in structural engineering is the design of simple basic components and members of a building viz., Slabs, Beams, Columns and Footings. In order to design them, it is important to first obtain the plan of the particular building. Thereby depending on the suitability; plan layout of beams and the position of columns are fixed.

Pile foundation

Sherchandra Shrestha

Pile foundations are commonly used when soil conditions require deep foundations, such as with compressible, waterlogged, or deep soils. There are various types of piles classified by function (e.g. end bearing, friction, tension), material (e.g. concrete, timber, steel), and installation method (e.g. driven, cast-in-place). The load carrying capacity of piles can be determined through dynamic formulas, static formulas, load tests, or penetration tests. Factors like pile length, structure characteristics, material availability, loading types, and costs must be considered for proper pile selection.

Purlins

sivasankar nikhil

Purlins are roof framing members that span parallel to the building eave and support roof decking or sheeting. They are supported by rafters or walls and spaced on main rafters such that roof sheets overlap by at least 150mm. Purlins are typically spaced between 1.35 to 1.4 meters and can be made of I-sections, channels, angles, or cold formed C or Z sections. Cleat angles, also called seat angles, are short lengths of angle iron used as brackets to support purlins.

Soil Bearing Capacity and Case study of Black Cotton Soil

Plate load test

Latif Hyder Wadho

A plate load test involves applying incremental loads to a bearing plate placed on the ground surface and measuring the resulting settlements. The test is used to estimate the settlement of a footing under working loads. A seating load is first applied and removed, then higher loads are placed and settlements are recorded until the rate of settlement decreases. Load-settlement curves are plotted from the results. The test gives the immediate settlement but not long-term consolidation settlement, so it is not very useful for predicting behavior in clay soils. The test also may not be representative if the soil is not homogeneous to a depth of 1.5-2 times the prototype footing width.

Base isolation

ARmiteshrank

Base isolation is a seismic protection system that separates a structure from its foundation, allowing the structure to remain largely motionless during an earthquake by absorbing shock through devices like friction pendulums and elastomeric bearings. There are various types of base isolators including low-damping rubber bearings, lead-rubber bearings, and sliding systems. Base isolation is most suitable for low to medium-rise buildings founded on firm soil, as it reduces seismic forces and prevents damage by permitting the ground and structure to move independently.
