Abstract Manysteelstructures are made ofstandardsteel sections designed and built in the traditional way. It leads to complex and expensive structures. Tubular steel sections are the best choice ofconventionaloneswithusefulpropertiesand relatively good. In this study analysis and design of 13 story industrial steel structure with conventional sections and tubular sections. A irregular floor plan at each floor is considered For modellingandanalysis ofstructuralmembers STAAD PRO V8i software is used. All structural members are designed as per IS code considering all load combinations. Static analysis and Time history analysis considered for seismic analysis and design of the structure. Comparison of analysis results on the basis of base shear, top story displacement, weight of structure. From the above study of analysis of conventional and tubular structure. It is understandable that tubular section is highly effective than conventional section that are subjected to lateral loading, to resist overall displacement and overall economy around 12 15% is achieved.

Key Words: Tall steel building, Time history analysis, Static analysis, Conventional section, Tube section, STAAD Pro V8i

1. INTRODUCTION

Population growth in urban societies and the continued constantpressureoflandhaveledtotheemergenceofvery high risebuildings.Tallbuildingsareconsideredasymbolof civilization. From a structural point of view, these are structures where their height will be affected by lateral forcesduetowindloadsandearthquakesuntilsuchpower willplayamajorroleinthedesignmethod.Theconstruction of high quality buildings is a challenging undertaking by professionals and engineers. In order to build a tall structure,onehastothinkaboutaprojecttobuilditsown design based entirely on limited design and analytical analysis.

As high rise buildings have greater prestige around the world, their impact on society and the economy is felt worldwide.Overtime,newbarrierstohigh riseconstruction are accompanied by growing demands for efficiency, efficiency,andeconomicstructure.Designersareconcerned aboutchoosingconstructionplansthatcancarryextraloads

as well as the availability of service and comfort requirements. The economic life of tall buildings depends largelyontheusabilityandeaseoflivingasarequirement. Typically, tall buildings are constructed to withstand extremely strong winds over a long period of time. The chancesofcatastrophicfailureareslim;however,studiesof wind movement and effects on high rise buildings are important from a service and economic perspective. The performance of tall buildings under wind is usually measured by the amount of side displacement and acceleration.Excesslateralremovalcancausestructuraland non structuraldamage,whileexcessiveaccelerationcanlead toimproperpostureofoccupants.

Common methods of construction have been found in the past,whichrestrictedbuildingstouptofivestoreys.These smallstructuresareoftenconsideredtobetheirstrengthto withstand horizontal loads and are designed for gravity.

From the above mentioned analysis of conventional and tubular structure. It is understandable that the tubular systemishighlyeffectivethanconventionalsystemthatare subjectedtolateralloadings.Thefollowingdiscussionhas beenmadefromthepresentstudy.

Fromthemodularinvestigationitcanbeinferredthat,steel tube structures are more adaptable than regular conventionalsteelstructure.

The tubular system is effective to resist the overall displacementthanconventionalsystem.

Above study reveals that tubular sections prove to be economical. Total saving of almost 12 15 % in cost is achieved. Tubular phase performance can be verified in differentpartsofthesystem.Membersofalargerstructure that are unsupported can be assigned to tubular sections thatwillbenefittheentireeconomy.
