Member Function Documentation

void compliance	(	double	t_current,
		double &	fi_t_t_dash,
		double &	fcyl_t_dash,
		double &	eps_shr_t
	)

The function computes compliance function. Parameters:

Parameters:

	t_current	is the concrete age [days]
	fi_t_t_dash	is the concrete compliance at time t since loading to t_loading [1/kPa]
	fcyl_t_dash	is the concrete strength in compression at time of loading [kPa]
	eps_shr_t	is the shrinkage at time t (from time_end_curing)
