Structural engineering - Essay ExampleThe analysis butt joint be done either manually or using commercial software. This paper is aimed at expand on the details of sub-frame structural design.For a span that is greater than or equal to two clock the overall depth for simply support span and greater than or equal to two and a half times the overall depth for continuous span, a beam is classified as alter beam, otherwise it is a deep beam.Effective width (beff) = width of beam (bw) + (0.2 times of half the essence to centre width to the next beam (0.2bi) + 0.1 times the span of zero minute of arc (0.1lpi), with the sum of the last mentioned not exceeding 0.2 times the span of zero moment and lpi taken as 0.7 times the trenchant span of the beam).Design moment of beam (and slab) monolithic with its support providing rotational restraint should be that at support face if the support is rectangular and 0.2 if the support is circular with diameter . But the design moment after redu ction should not be less than 65% of the support moment.For a simply supported or continuous beam, the polish off distance between restraints should be less than or equal to 60bc or 250bc 2/d if less and for a cantilever with lateral restraint only at support, the clear distance from cantilever to support should be less than or equal to 25bc or 100bc 2/d if less where bc is the breadth of the compression face of the beam and d is the effective depth. Usually the leanness limits need be checked for inverted beams or bare beam (without slab)We can, as far as our building structures are concerned, roughly adopt particularise 1 (Mild) for the structures in the interior of our buildings (except for bathrooms and kitchens which should be condition 2), and to adopt condition 2 for the external structures. Nevertheless, the Code of Practice for Fire Resisting Construction 1996 should also be checked for different fire resistance periods (FRP). So, taking into account our current practice of using concrete not inferior than
