However, other measures such as wall, roof...

Even though membrane structures have been increasingly used in the world, their energy efficiency is very unfavourable due to poor thermal properties.This causes relatively high consumption of heating winter, as well consumed for operation air-conditioning during summer, that is, under circumstances which require comfort.Since comfort depends on air temperature and interior surfaces envelope, this paper presents a study measurement comparison temperatures single double summer period.Data...

Point loading has so far received insufficient attention with regard to its influence on deflections of the membrane structures, although it occurs relatively frequently. It can appear most commonly during maintenance as live load, or dead load incident load. In practice, engineers investigate point effects for their structures relying mostly own experience; an extensive analysis this problem is, our knowledge, yet unavailable. This paper presents research dealing position and intensity...

Tensile structures are currently the most advanced lightweight structures. Apart from their very small self-weight, they also characterized by a double curved form with negative Gaussian curvature.
