Structural nalysis and Design of

Multistoreyed ramed Buildings

I. INTRODUCTION

Continuous frame analysis is a very important design subject for a

structural engineer, for in this field he is confronted with the conflicting

requirements of achieving sufficient accuracy and at the same time expending a

minimum of effort and calculation. or this purpose there are many analytical

procedures established and evolved by eminent persons like Castigliano,Clapeyron, Maxwell, Poisson Hardy Cross, Grinter, Kani and so on. In the

presence of these the aim of writing this paper is to lay down in a simple form

a procedure for adopting suitable methods, which may be easily understood,

and are also comprehensive enough to so lve the various problems, that arise

in designing complicated framed buildings. Construction of a number of such

buildings are in progress under the charge of the author at Lahore, and he has

the opportunity of structurally designing a number of these. He has, therefore,

ventured to sum up his observations in the form of this paper, so that it may

be of some use to those who are interested in the design of multistoreyed

buildings. While tackling this problem the paper deals with, in the beginning

various properties of a rigid frame and different kinds of loads to which it is

subjected. l t then gives various methods of stress analysis, finishing in the

end with illustrations for stress analysis, which are self explanatory.

The scheme for the construction of Government Institute of Polytechnic

at Lahore was approved by the Government of West Pakistan at the estimated

cost of Rs. 31 lacs. The site selected by the department for this purpose was

the premises occupied by the existing Government Technical Institute at

Railway Road, Lahore.* The site being limited, the new building has been

planned as five-storeyed structure consistent with architectural, structural

and functional requirements, so that it is suitable from the point of view of

accommodation, convenience and comfort. The structure is fully rigid and the

frame that has been adopted consists of two or three panels having long

verandahs with rooms flanking on one side only. The site where the Polytechnic

building is being constructed consisted of made-up soil up to 5 depth. Boring

was carried out at different places up to 100 depth which revealed that the soil

below IS was satisfactory.· · · - -• S uperintending Engineer Constmctio11 Circle Lahore.
