Comparative Study on Two Storey Car Showroom Using Pre-engineered Building (PEB) Concept Based on British Standards and Euro Code

Abstract

Majority of steel structures are used for low-rise single storey buildings mainly for industrial purpose. Steel structures are preferred for industrial buildings due to its higher strength to weight ratio as compare to RCC structures and steel structures also gives more free internal space by allowing long clear span between columns. Pre-engineered building (PEB) is a modern age concept of utilizing structural steel and optimizing the design by ensuring the economical integrity of the structure. The structural members are designed and fabricated in the factory under controlled environment to produce optimum sections by varying the thickness of the sections along the length of the member as per the bending moment requirement. The aim of the research paper is to analyses and design a PEB car showroom of two storey (G+1) using STAAD Pro in accordance to British standards (BS 5950-1:2000) and Euro codes (EC3 EN-1993-1) with wind and seismic analysis. In order to achieve the above aim of the project, two models of the car showroom were created namely British Standard (BS) model and Euro code (EC) model using STAAD Pro. The member property for BS model is assigned with tapered frame sections while the EC model is assigned with universal standard section frames. The load cases were assigned to the models for analysis include dead load, live load, wind load and seismic load. Wind load and seismic load being the critical dynamic loads that will be analyzed for the stability of the structure against lateral forces. The results from the analysis and design of the two models were within the allowable limits for ultimate and serviceability limit state since the internal stresses in all the members satisfies the unity check ratio requirements for both design codes. The dynamic analysis results suggest that EC model has higher resistance to seismic loading as compare to BS model since the maximum displacement with time in X-direction for EC model is 8.83 mm and for BS model is 10.5 mm. The total weight of the structure for BS model is 1125.431 kN and for EC model is 1214.315 kN, which makes EC model 7.9% heavier than BS model. Moreover, the total weight of all the portal frames for BS model is 457.26 kN and for EC model is 574.725 kN, which makes tapered frame sections to utilize and reduce the amount of steel by 25.7%. Therefore, BS model proved to be an economical model when compared to Euro code.

Strengthening of Edge and Corner Columns using Concrete Jackets

“…A three main elements were needed for the modelling, concrete element, reinforcement bars element and the interface between the original column and the concrete jacket. The concrete was modelled using Solid 65 element, Figure 1 show the element discretion from ANSYS [23], the steel bars and horizontal stirrups were modelled using link 180 elements [20,23]. A column concrete geometry, steel bars, stirrups, and a jacket are all included in the model.…”

Effect of Fiber, Cement, and Aggregate Type on Mechanical Properties of UHPC

“…The UHPC mix developed in this study used a combination of fine sand (FA), ultra-fine recovery material (UFR), cement, and different supplementary cementitious materials (SCMs), including slag cement (S) and silica fume (SF). Previous studies also reported using fine quartz particles in the UHPC matrix [19,22,23,30], but quartz is not locally available in Florida, with the majority of produced sand in this state coming from limestone aggregate. Silica powder was not used due to its relatively high costs.…”

Analysis of Earthquake-Resistant Portal Frame Structures with Ordinary Moment Frames (OMF), Intermediate Moment Frames (IMF), and Special Moment Frames (SMF) based on SNI 1726:2019

“…Another research is to discuss a comparative study on a twostory car showroom using the pre-engineered building (PEB) concept based on British Standards and the Euro Code. The analysis compares structural behavior in terms of earthquake resistance, structure weight, and building stress ratio [9].…”
