If a landlords property destroys the tenants property which party is liable

The nebulous answer is: it depends.  Many lease agreements provide that the tenant is liable for any and all property damage (including fixtures) within a rented premises.  Therefore the first place you need to look it in the Lease Agreement for allocation of responsibility and maintenance.  The second issue which you need to address is whether the Landlord had knowledge and/or caused the chandelier to fall or whether the Tenant caused the chandelier to fall.  In many cases, this is where Tenants will simply turn the matter over to their insurer and have Tenants' insurance and Landlord's insurance haggle over coverage because the amounts in controversy make detailed litigation over the table cost prohibitive.
