Requirements: Usage class NKL 1 (interior rooms kdef = 0.8), permanent load g1k: permanent structural load without net weight of CLT BBS (this has already been taken into account in the calculation) Live load nk: categories A and B (residential and office space: ψ0 = 0.7 ψ1 = 0.5 ψ2 = 0.3 load duration medium, kmod = 0.8) Fire design according to EN 1995-1-2 and expert opinion IBS-319072401-1 (charring rate for ceilings βn = 0.9 mm/min) Vibration requirements subdivided according to DKL 1 and DKL 2. Cross-sectional values: Calculation of CLT BBS cross-sections according to EN 1995-1 using the gamma method (flexible composite). For continuous beams leff = 4/5 * l These tables are used for pre-measurement of CLT BBS and do not replace static calculations. The characteristic loads have been applied as uniformly distributed loads. The length of the shorter field is between 80% and 100% of the longer field. > 0,8 * L One field Two field CEILING DESIGN IN MULTI-STOREY BUILDING CONSTRUCTION (DKL 1) BINDERHOLZ CLT BBS | PRE-MEASUREMENT > 0,8 * L One field Two field CEILING DESIGN IN SINGLE-FAMILY HOMES (DKL 2) DKL 1 (ceiling class 1) - Ceilings between different usage units (also continuous) - Use as apartment partitions in multi-family dwellings - Ceilings in offices with PC use or meeting rooms - Corridors with short spans DKL 2 (ceiling class 2) - Ceilings within one unit of use - Ceilings in single-family homes with normal use The length of the shorter field is between 80% and 100% of the longer field.
