5.1 SUMMAR8: T!e researc! %as to study about temporary e,!ibition structures" As a first step all t!e terminoloies related to suc! structures& different parts of a temporary structure & different types of temporary structures& t!eir ad$antaes and disad$antaes& different types of membrane materials& construction of temporary structure& Air conditionin and li!tin inside a temporary structure %ere studied" Usin t!e secondary data ; main types of temporary structures are listed & and comparin t!ese t!ree types on t!e basis of cost & ris'iness of construction &span& climatic suitability& time of erection and dismantlin& 5oundation re)uirements and !ei!t & it %as found t!at temporary structure made %it! aluminium structural members and fabric membrane materials suc! as tarpaulin& nylon and polyester is more preferable"

5.2 INFERENCE: T!e 7i$e case study s!o%s t!at t!e temporary fabric structures can be constructed in t%o %ays con$entionally& namely barrel roofed structure and able roof structure" only t!ese t%o types of structures are found economical in our conte,t" Table :"1 s!o%s t!at barrel structure are more e,pensi$e t!an t!e able structure" And t!e barrel roofed structure can !a$e more span appro,imately 6?m %!ile t!e able roofed structure %ill not be stron to %it!stand %ind loads and ot!er loads %!en t!e span e,ceeds 6.m " 9!en comparin t!e barrel and able structure in terms of time ta'in for t!e construction& dismantlin and t!e ris'iness of construction& t!e able roofed structure is more preferable as its ta'in lesser time to erect and dismantle" And t!e ris'iness is comparati$ely $ery lesser


t!an t!e barrel structures because t!e arc! units used for t!e construction of barrel roofed structures are more !ea$y t!an t!e rafters and purlins used for t!e able roofed structure" Table :"6 s!o%s t!e cost comparison of 3embrane materials used for t!e temporary structures" 5rom t!e data collected t!rou! literature re$ie% & it is clear t!at t!e more e,pensi$e membrane material is Fe$lar and %!ic! is rarely used for t!e s!ort term temporary structures" Nylon s!eets& tarpaulin and polyesters are preferred as membrane structures for temporary pa$ilions T!e studies s!o%s t!at e$en t!ou! t!e fibre lass is lesser e,pensi$e t!an t!e Fe$lar s!eets &it can increase t!e !eat inside t!e structure" 9!ic! leads to t!e need of air conditioners more capacity and t!ereby increasin t!e cost" It is found from t!e literature studies t!at ot!er t!an t!e con$entional met!ods of assemblin and desins it is possible to desin structural components and /oints of different s!apes and ma'e a modular temporary structure" 5rom t!e abo$e studies it is found t!at able roofed structures are preferred to reduce t!e cost of construction and t!e time of erection and dismantlin& and semicircular or barrel roofed structures are preferred for lon span structures"

5.3 CONCLUSION: 5rom t!e studies it is found t!at fabric roofed structures are preferable as it is cost effecti$e and t!e time of erection and dismantlin is $ery less" polyester & nylon and tarpaulin are preferred structures" poly carbonate s!eets and steel clad roof structures are not preferred as t!ese types of structures are found $ery costly from t!e literature studies" it is found from t!e literature studies t!at ot!er t!an con$entional tec!ni)ue of construction& temporary structures can be constructed as modular structures& %!ic! can be carried from one site to t!e ot!er" Terminoloies used in temporary structures& different parts of a temporary structure& Different types of temporary structures and t!e occasions in %!ic! t!ey are used& t!e c!oice of appropriate desin and materials & construction tec!ni)ues of temporary structures& proper plannin and control of %or' practices& positionin on t!e site includin round conditions and foundations etc" are studied"
