wind uplift การใช้

• The floor of the service catwalk is 110mm thick concrete acting as ballast to resist wind uplift.
• The older organic ( wood and paper pulp product ) versions were very durable and hard to tear, an important property when considering wind uplift of shingles in heavy storms.
• Hook fixing is especially prevalent in areas subject to severe climatic conditions, since there is a greater resistance to wind uplift as the lower edge of the slate is secured.
• Additionally, the association has sponsored and led research into bolted end plate connections, cold-formed steel, snow loads and wind uplift, and insurance issues for metal buildings, among other topics that are pertinent to the industry.
• In order to accurately design an OWSJ, engineers consider the joist span between bearing points, joist spacing, slope, live loads, dead loads, collateral loads, seismic loads, wind uplift, deflection criteria and maximum joist depth allowed.
• In order to accurately design a pre-engineered building, engineers consider the clear span between bearing points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection criteria, internal crane system and maximum practical size and weight of fabricated members.
