Holotype ♂ and paratype Ψ from Poções, Bahia, Brazil, (deposited in IBSP 3394 and 3395, examined). Souza et al, 2006: 28, 35; Lourenço, 2006: 60. New record. Brazil, Bahia: Rio de Contas (Pico das Almas), 871m, 13 º 35 ’ 60 ’’S 41 º 47 ’ 60 ’’W, 11.IX. 1991, M. Trefaut U. Rodrigues leg., 1 Ψ (IBSP 2577). Diagnosis. Male. This species differs from the others of complex by the presence of three dark brown longitudinal stripes on tegites, except by T. martinpaechi and T. stigmurus. Tityus aba can be distinguished from T. stigmurus by a different pattern of pigmentation, with carapace almost entire dark (Fig. 1 A–B), three longitudinal dark brown stripes on tergites which begin at the posterior edge of the carapace, the lateral ones reaching the VI tergite and the central reaching the VII (Fig. 1 A–B), a largest number of pectinal teeth (male 25 –25, 26–25, 26– 27) and greater total length (76,5 mm) (Candido et al, 2005), whereas T. stigmurus has a single longitudinal dark brown stripe on tergites which reaching the VII tergite, carapace with only one triangular dark brown spot on anterior region (Fig. 16 A–B), small number of pectinal teeth (22, 23– 24) and smallest total length (60,3–63,8 mm). It also differs from T. martinpaechi by a different pattern of pigmentation, without sparse dark brown spots on carapace, palps, legs, morphology of the palps and metasomal segments which are slender (T. aba = femur: 8.3; tibia: 8.7; chela: 14.9; fig. 9 A–B; T. martinpaechi = femur: 7.2; tibia: 7.4; chela: 13.3) and a largest number of pectinal teeth (T. martinpaechi: 22 – 21). Female. Same color pattern as the male (Fig. 1 A–B). Morphologically differing from the male, by the shorter chela of the pedipalp (length female: 13.3mm; male: 14.9mm) (Fig. 2.A–B). Metasomal segments IV and V longer and closer (IV: female 9.7mm and 4.5mm; male 9.3mm and 5.6 mm—V: female 10.2mm and 4.2mm; male 9.3mm and 5.0mm) and total length (female 66.1mm and male 76.5mm) (Fig. 1 A–B) (Candido et al. 2005).

No full textOn the benefits of using in the joints of R/C frames subjected to seismic loading
No full textThe extensive research activity carried out in the last few decades on fibre-reinforced concrete is showing - beyond any doubt - that FRC has very interesting properties for structural applications. The dispersion of short fibres - made of steel, polymers, carbon, etc. - in the concrete mass brings in a 'crack bridging' effect, which prevents or delays cracking, and – at the same time – provides concrete with a ductile behaviour both in tension and in compression, given that relatively large amounts of stiff fibres are used (as for example in high-performance fibre- reinforced concretes - HPFRC). As a result, the use of such concretes significantly improves significantly the structural performance of R/C members, not only under static and fatigue loading, but also under dynamic and seismic loading. However, considering their higher costs and more complex technology, high-performance fibre-reinforced concretes are only suitable for critical areas of R/C beams and columns, as well as in the beam-column joints of R/C frames, where the actual Italian code (2008) may require an excessive amount of reinforcement, even in the design of low-ductility members.
Within this context, this paper investigates the benefits of using high-performance fibre-reinforced concretes in the nodal and inelastic regions of R/C seismic-resistant plane frames are investigated in this paper, focusing on typical frames which are commonly found in residential buildings, with two-four bays and two-eight storeys. Ordinary mixes (C25/30 and C40/50) are adopted for frame members, while higher-performance fibre-reinforced mixes (FRC40/50 and FRC80/85) are used in critical areas and in the joints. The joint regions are modelled with or without rigid end-sections and in-plane stiffness of the floors is introduced as well. The frames are designed according to the actual Italian code (NTC08) and to EC8. In the nonlinear static analyses, considering either triangular or uniform load profiles, a diffused-plasticity model is adopted for frame members. In terms of global capacity and ductility, the use of HPFRC - instead of plain concrete – offers considerable benefits
