“…This effect is also emphasized in Table 3, where the mean experimental ∆ f estimates (i.e., average results grouped by p) are not linearly proportional to p. Based on the dimensions of the panel (1.65 × 2.65 m 2 ), in this context, it can be reasonably expected a frequency increase up to ∆ f = +15%-20% for the occupied structure (under similar ambient conditions). As far as the "added mass ratio" R M is also taken into account, with: (5) in Table 3 it can be also noticed that live loads are generally relevant, hence a further increase of dynamic effects and human perceptions can be expected (see Section 5.3). In terms of damping, see Figure 9c and Table 3, the presence of standing/walking people increased up to two times the capacity of the empty structure (ξ es = 1.15%).…”

“…This is also the case of glass structures under dynamic/impact loads, or complex systems and glass stairs ( [4][5][6][7][8][9][10][11][12][13][14], etc.) where-in addition to conventional safety design requirements ( [1,2] and Section 2)-excessive vibrations may involve unfavorable feelings and require dedicated interventions, at the design stage as well as during the service life.…”

The vibration performance of pedestrian structures attracts the attention of several studies, especially with respect to unfavorable operational conditions or possible damage scenarios. Given a pedestrian system, specific vibration comfort levels must be satisfied in addition to basic safety requirements, depending on the class of use, the structural typology and the materials. To this aim, guideline documents of the literature offer simplified single-degree-of-freedom (SDOF) approaches to estimate the maximum expected vibrations and to verify the required comfort limits. Most of these documents, however, are specifically calibrated for specific scenarios/structural typologies. Dedicated methods of design and analysis, in this regard, may be required for structural glass pedestrian systems, due to their intrinsic features (small thickness-to-size ratios, high flexibility, type and number of supports, live-to-dead load ratios, use of materials that are susceptible to mechanical degradation with time/temperature/humidity, etc.). Careful consideration could be then needed not only at the design stage, but also during the service life of a given glass walkway. In this paper, the dynamic performance of an in-service glass walkway is taken into account and explored via field vibration experiments. A set of walking configurations of technical interest is considered, involving 20 volunteers and several movement features. The vibration comfort of the structure is then assessed based on experimental estimates and existing guideline documents. The intrinsic uncertainties and limits of simplified approaches of literature are discussed, with respect to the performance of the examined glass walkway. In conclusion, the test predictions are also used to derive “perception index” data and scales that could support a reliable vibration comfort assessment of in-service pedestrian glass structures.

Architectural design concepts incorporating glass beams, panels, or generally load-carrying elements and sti eners for buildings, claddings, windows, and partitions are largely considered in modern high-rise constructions. A multitude of aspects, including motivations related to transparency, aesthetics, illumination, and energy conservation, progressively increased the use and interest for such a still rather innovative constructional material. However, compared to other traditional materials for buildings, standard glass is typically characterized by brittle behaviour and limited tensile resistance. e intrinsic properties of glass, moreover, together with typically limited thickness-to-size ratios for glazing elements, or the mutual interaction of glass components with adjacent constructional elements as a part of full assemblies they belong (i.e., xing systems, sealants, etc.), as well as the combination of mechanical and thermal phenomena, make glass structures highly vulnerable. Special safety design rules are hence required, especially under extreme loading conditions. In this review paper, a state of the art on structural glass systems exposed to re is presented. Careful consideration is paid for actual design methods and general regulations, as well as for existing research outcomes-both at the material and assembly levels-giving evidence of current challenges, issues, and developments.
